Ive recently built my new system which is a 975badaxe, 805d with 2x1GB Patriot 667 (Model #: PDC22G5300LLK) and on newegg ive read people getting 800mhz on 1.9v at 3-3-3-12, well ive tried to obtain this with my mobo, and it wont post, wont even give beep errors, but the odd thing is, is that i cant even run this at 667 on my mobo, when i try to run it at 667 it gives me a no memory beep error. Ive also tried to turn the latency really high on both the 667 and 800mhz clocks and still nothing. Please help...

Check out the FSB strap, it may have something to do with it..not sure since I have never actually tried Intel

Did you also raise North Bridge voltage?

imma go look in my bios for the options, i havent done the pen mod yet so i dont know if those will show.... brb

well i looked in my bios menu and all that i saw i was able to change was the North Bridge voltage, and i gave me 4 options :
DEFAULT
1.395 v
1.333 v
1.271 v

i dont know how much my default North Bridge voltage is atm and i check my hardware monitor and it dosent specify directly the North Bridge voltage. I havent changed it yet, should i try all low and start up? i dont want to burn up my north bridge

Starting low and raising it is the way to go...I would also try raising the Mem volts..ususally up to around 2.2~2.3 volts is "Safe" with decent airflow in the case (Dead air, as in no fans, would not be a good idea!)

SOmetimes "Speed Fan" (google it) can read the NB temps, depending on the motherboard...my rule of thumb for just about any temp in a PC is 50c or less

necro, i have to let you know, im scared to touch my volts, but ill go ahead and do so on the nb.... but about the memory, its designed to run on only 1.8, would 2.2 not burn it up? if i burn something up, i wont have money to fix.... maybe i should oc 1 stick of ram first then stick 2 in once i can get the first one right?

I understand you are nervous about raising the voltage..but to let you know the only time I have ever hurt ram is when I got TOO crazy with it!

Running 3.1v in my TCCD DDR600 to make it run DDR740 when everyone said not to go over 2.8-2.9v....2.5v is stock for DDR-1

With BH-5 RAM, I was able to use 3.6v cause it realy LOVES voltage and could take it over prolonged use..I was able to run it at DDR 540 with 2-2-2-7 timings...it was origianlly rated at DDR333! (That was with a fan blowing on it to keep it cool, normally 3.2v is all you want to use)

Now with DDR-2, there are KNOWN issues with the stock volts being too low...so 2.0V should be enough to get the job done safely..2.2-2.3v is what some high end ram is rated for as "Safe" and under still under warranty..so I would not even sweat going to 2.1v!

I have heard and seen people using up to 2.5v on DDR-2 with a fan blowing on it, but that is not something I would reccomend for long term use!

Now I have been at this for a few years now..if raising voltages killed hardware..I would not be able to post on my old Mobile 2500+ still like I am now!



1.85 CPU volts---have used up to 2v on this old 130NM Athlon XP CPU at 2.7GHZ (1.6v stock)



I am using Phase Change on the background Image from this screenie of the Mobile..the 90NM 3100+ Sempron under there is 1.8GHZ stock, running at 3GHZ with 1.85v (1.35 is stock..but notice the -45c temps!)

well.... ive ran my memory on every single voltage, and my mother board still wont accept a slow timing from 667mhz or 800 mhz, and also i mixed up earlier when i gave those voltage options..... well those are my fsb voltage options, not my north gate voltage.... and well i guess that option will be avaliable once i get the conductive pen mod done to my board.... im gonna go by a place tommorow to pick it up before school hopefully....

Yeah..the bad axe boards are funny..they realy need the mods to work right..we need Cpt. Planet or Big Akita to help if you can't figure this out!

cant seem to find anyone who sells a conductive pen locally.... gotta keep searching, i dont want to use solder on my mobo...

Go to the auto parts store and get a 10$ or less "Rear window defroster repair kit"

That will have what you are looking for inside

So I take it you're running at 533? If it won't post at 667 with stock SPD values you should RMA it. It sure won't run at 800 no matter how much juice you pour into it.

man.... ill think about it, i need to see howmany days are leftk, man im deunk right now and i will hit ya bvack latrer about that.

I would think they may give him some grief if the ram is not on the motherboards "Approved" list...I kinda doubt that it is!

I wonder if Patriot certifies ram for comaptibility of Chipsets/CPUs?

I don't think I have seen this come up very often lately, but it seems to me back in the early days of AMD-64 and P-4's they would often spec two sets of timings...come to think of it, they also had a different ratings for AMD XP's and P-4's.

EDIT:
Ok..here is what links I have found:

So basically you are hosed..it is not supported "Officialy" for it's rated speeds on Intel 775 chipset based motherboards!

In fact..there is no listing for ANY DR-2 800 supported ram what so ever for the 975 chipset at the Patriot website!

They only list these Modules:

Necro...what the hell are you talking about bro'?

Dude, read the first post. He bought DDR2-667 ram. It won't run at 667. If it's rated at 667, a ram speed the 975 chipset does "officially" support. If it won't run at that speed all he has to do is return it.



It's got a lifetime warranty.


RMA it.

Then, if the new stuff doesn't run at 800, well ...he didn't buy 800 now did he?

OUCH!

The ram is not "Officialy" supported rated for the 975 chipset....Yes the board does support that speed, but his ram is the "Low Latency CAS 4-4-4-12 " version of DDR-667...not the standard 5-5-5-15 of typical ram.

I realy don't wanna get into an argument with ya about it, but I could not find it anywhere..where exactly did you see it supports his specific module?

Only support for the 955 and NF-4 chipset is listed.

My point with the DDR800 stuff was Patriot does not even make a module that will "Officially" support that speed on that chipset...something I found quite surprising considering just about all the other major brands do.

And in testing some of Digi's 975 Gigabyte board with DDR-2 667 from OCZ, I was able to get it (After coaxing him into it) to run at DDR-2 800 speeds with a bump in voltage to around 2.0-2.2v (Can't remember exactly since I was not the one making the changes in the Bios)

If you look around at some of the issues with DDR-2 low latency ram, the default Bios voltage is often not enough to get the job done with certain modules, alot of the ram wlll only run at the "Rated" speeds and timings only after you bump the voltage up from the stock 1.8v since some board undervolt a bit.
Or...you can relax the timings a bit.

Here is an example:

Brand	Crucial Technology
Series	Ballistix
Model	BL2KIT6464AA663
Type	240-Pin DDR2 SDRAM
Tech Spec
Capacity	1GB (2 x 512MB)
Speed	DDR2 667 (PC2 5300)
Cas Latency	3
Timing	3-3-3-12
Voltage	2.2V

Cons: A little trouble with install, motherboard default voltage was 1.8v (actual 1.75V). This memory needs at least 1.8V to get through POST. Rated for 2.2V, check your motherboard's actual default DIMM voltage not just the stated default.

Pros: Works flawlessy after setting the right timings in the bios.
Cons: Would not even boot with auto dram settings.

Cons: would not run at advertised clocks at stock speeds, at 533 it wont runs below 4-3-3-14
fairly dissapointing

Comments: Amazing memory - have this in a new Pentium D system. Running DDR2 800 specs at 4-3-3-13 at 2.1 V. Truly Amazing. Will never go back to any other brand!

The last comment brings home the fact it will often perform at much higher rated speeds than stock by raising voltages beyond the standard 1.8v

Here are some intresting comments about some Patriot 667:

Cons: Call patriot about the warranty. The warranty is VOID, if you change the default timings 9EVEN IF THEY SHIPP WITH THE TIMINGS SET LOWER THAN ADVERTISED!!). I finally got this from a friend for cheap. Now I know why its cheap. Only works for 3-4 days. Then messes your DIMM slot and commits suicide. So I BASICALLY HAD TO REPLACE MY Asus P5W Dh motherboard too. Total disaster cost = $495. Latest modelues coming out dont even go beyond 700MHz. Waste of money. Go with Kingston.

Other Thoughts: Newer modules coming out are locked (I found that out the hard way) because the new set I ordered from a very bad place (Thats why you should always order from Newegg, or you be left with nothing at all), worked for only 2 days, then 1 died, RMAed it and the new one I got (had to pay half price!!??? for warranty replcacemnt) and that cannot be overclocked at all. Asked a couple friends who had this. Same story. NEW MODULES ARE LOCKED. NO OVERCLOCKING AT ALL. NOT WORTH. Go with kingston.

Other Thoughts: Bought with an Asus M2N-E and I can't boot the memory at 667. I have to clock it down to 553 to boot.

Jeez Necro, you are way over thinking this. You're telling this guy who asked for help from "experts" that he is just going to have to live with bad merchandise? I don't try to tweak bad merchandise. I send it back and get something that works the way it is advertised to do ...then tweak it.


If the module doesn't run at the advertised speed as defined by the numbers programmed into the SPD at default JEDEC voltages it is faulty. Period.

It doesn't matter if the chipset has been validated for the module or not. It's not like they are going to come out to your house and check which chipset you're using. And motherboard manufacturers generally do the validation, not the ram makers.

I've never had a manufacturer not replace a module that did not run at it's rated speed. They may try to talk you out of it, but they will replace it.

I am not saying he has to live with it, but I doubt an RMA will solve the problem*

It's just not comaptiable with his board to run at those speeds for one reason or another...I have some Corsair XMS PC 3200 that runs like crazy on my N-Force 3 at up to DDR500 speeds, but when I put it in my Shuttle AN-35 Athlon XP rig..it won't even think about booting at DDR 400 at the rated timings of 2-2-2-5 with 2.7v.

Hell, it even works in every other board I have tried, but for some reason no matter what I have tried, it doesn't wanna play nice with this board!

This same board ran fine with older XMS that was rated at PC4000, and could even reach DDR 480 speeds with some Geil PC4000. That Geil however would not even boot in my NForce 4 board unless I manually set it to run at 2T timings, I suspect it was in the SPD timings not being compatible with the specific chipset.

I am thinking that is the same issue with the XMS 3200 and this board, I would bet it's trying to use 1T and my chipset says Nuh-Uh!

The reason I supsect that, is there is no "CPC" option in the bios to set this manually. When I use BH-5 in this board and use CBID to set it to 1T once it's booted up, it flakes out and crashes!

And yes..I may tend to overthink things at times, but I would bet money he will never get that ram to work on his board at the rated speeds or timings.

*So, go ahead and RMA the ram as suggested by AntiM, and if it still does not work at DDR 667, then you can see if they will swap it for something that will...it's possible that a newer revision my use different chips under the heatspreader, or have revised SPD timings that may work.

I don't suppose you have a buddy with a rig that uses DDR-2 that you can swap back and forth with to see if they work in his rig?

Your other options would to be to sell it on EBAY or the Forums here, and then purchase another brand of ram that is on an approved list to ensure it works..it would seem leaving it run at DDR-2 533 speeds is not making you a happy camper.

Intel and ASUS baords are among the most picky you can find when it comes to choosing ram!

So are you saying his motherboard is borked? Because there are people (newegg comments section) running this ram as high as 800 on the same board.

Easy way to tell, pull out one stick at a time and try again. Chances are if I'm right, then at least one of the sticks will boot at the standard SPD timings at 667.

That is a possibility, but I don't think that is the case here..I think the ram and board are just fine..they just won't play well together.

I would bet if you tried that ram in another board it would run at DDR2- 667 and beyond, and if you tried a different model ram in his 975 Axe board, it would aslo run at DDR-2 667and above.

Cause yeah..that ram is supposed to run like hell...DDR 800 speeds and tight timings according to the customer reviews is what I saw too..and since it seems to work fine at DDR-2 533, and does not respond to higher voltage, it smells like an incomapatibilty in the motherboard and ram SPD timings.

Trying them one stick at a time is a great suggestion!

If you go back to my original post about the FSB strap settings..it seems that they have something to do with motherboard latency settings in the NB if I was able to follow them correctly..

Quote: But, what is really interesting is that why is 3.7GHz with 14 x 266 settings is extremely stable versus 3.63GHz with 11 x 333 unstable? With just lower FSB and higher clock frequency, and higher FSB but lower clock frequency, the system has been acting differently. Does this mean that vCore is not an issue? Since at 3.7GHz, all set on default, clearly, there is no need for a vCore increase with just 3.63GHz, at least, not on the CPU and Chipset which are all tested to run on "auto" settings even beyond specifications (390FSB for Chipset and 3.7GHz for CPU).

Intel® D975XBX EPP[Extreme Processor Profile]? (Uber Motherboard for Intel® Core™-based Processors)

Now what strikes me here, and is what is leading me down this path, is that the "Strap settings" with his ram at 533 are probably MUCH diffferent then when he tries to run at 667!

The CPU speed will stay the same, but the NB timings will change and cause it to have fits!

Maybe I AM overthinking this here, but it sure sounds reaaaaly similar..with Non- OC'd CPU settings...but different ram speeds....things get weird! (Especially with low latency ram I would bet)

Again, this is long haired reading and without my own hardware to test with..it is hard to verify, but I can smell somthing going on here that is not as simple as it may seem on the surface.
