Ram scaling with temp

[Somerandomtechyboi]

Yesterday i wanted to go play around with my extreem dark ddr2 1520 oc and see if i can get a proper 1520 speed that doesnt have nuked subtimings so i can make a vid out of it but apparently when i tried the last setting it didnt work even when i had a fan over the rams so kept on having headaches for the rest of the day wondering why in the fk my ram oc wasnt stable and used an earlier profile with 1520 7-9-9-12 at 2.26v, kept on erroring in prime95 large ffts so raised nb volt and it helped abit but it still errors, even tried raising fsb term which helped slightly but still errors, gave up near midnight and decided to go sleep and continue tomorrorow

 

Today i decided to move the fan to cool the nb more to see if that helps cause raising nb volt did restabilize the rams, nope, tried the 7-9-9-12 profile and still nope, this time crashing after 2 mins instead of 30 mins or something, kept tweaking nb and fsb volt to no avail, but then i figured out it was the damn cooling cause thats the only thing that changed, so moved the fan over and added another fan to blow over the other side of the ram and whaddaya know, now 7-9-6-10 runs stable at 2.34v at the settings i left off with last time

 

 

Yes i did use an intel fan cause thats the only other small fan i had laying around

 

The rams didnt even feel that warm even on the other side that didnt have direct airflow so never gave a second thought that cooling would be the problem

 

 

Guess some rams really scale with temp, and this nanya d die is one of em, even shoving more ram volt didnt help but these rams dont scale that well with volt in the first place unless im tweaking the timings, its mostly temp scaling

 

Basically if you run into issues with your ram not going higher freq even if you crank all the other volts and made sure your timings are not limiting you then you are prob running into a temp limit and you gotta add (more) cooling to your rams

 

I hope my 8 hours wasted can now save someone from wasting their time xD

 

Next up i think ill get micron d9s after i get my x58 rig setup with triple channel ram for the fah comp, hopefully i can score dome d9gkx for higher freq but i may have to settle for high freq cl5/6 overclocks, for all i know d9 is supposed to scale well with voltage so if temp isnt an issue then ill give 2.95v oc a shot  but for now if 7-9-6-10 is stable for a few more hours or crashes ill continue on tweaking the timings so it doesnt perform like garbage cause the secondaries and tertiaries are nuked atm, ill also shove the 3000rpm cpu fan onto the rams so it has more use than just making the thing noisy

There's just a lack of substance to all this. 

Multiple threads, talking about hardware nobody uses anymore and we don't even know what you are using. All we know, it's a DDR2 system, 3GB in dual channel. Running Prime95. 

 

If you're memory overclocking, why not benchmark your results to the different settings you try by running PiMod 32M instead of beating a dead platform with Prime95?

Could you reccomend ram benchmarks i can use? There is no point in ram oc if the performance is garbage, but atleast i have m a x i m u m f r e q u e n c y s p e d b o i r a m thats stable and even dailyable (volt is low)

 

The ppl on warp9 say my rams are garbage even at this speed cause the timings are trash, i agree considering these rams only do 6-8-5-10 at 1300, iirc volt was ~2.2-2.3v while d9gkx can do the same but 5-5-5 timings, apparently they can even do 1100 4-4-4 so these rams look like complete garbage compared to d9, but hey 1520mhz at 2.34v isnt that bad

Yeah, I suggested PiMod 32M. That is a CPU and Memory benchmark. Use that. When you start shaving off time, your getting better performance. 

 

Also, you could try different processors. That would be binning the CPU (and memory controller). Sometimes you find a chip that handles memory better than others.

 

I'd say 1200mhz CL4-5-4 or tighter, then work higher the memory frequency.

 

Them dudes at Warp9-systems really know their stuff!! I was just checking out their forum. It's packed full of good information!!!!

This what i consider garbage p5q is the best binned p5q ive found so far as all the others are trash, so the only thing capping it to 490fsb is prob the cpu though i do wanna get an e8600 as a replacement, for all i know i should be aiming for <1.4v 4.5ghz or <1.6v 5ghz for a good sample

Yea thats not happening, cant even get anywhere near 1200 at 5-6-5-10, need good d9gmh/gkx for actual performance as those actually scale with voltage so i can shove tons of volt into them and still be scaling just like my ddr3 samsung rev f that i cranked to 2.46v, 2.95v is ideal but i doubt my cooling will allow me to scale that high if i ever get d9gmh/gkx generic rams

 

I can only aim for high freq on these rams

Yea it has been a treasure trove of good info on old hardware and more exotic modding like epower, voltmodding, general hardware modding pretty much

I have some Blue G.Skill PC8500 5-5-5-15 sticks that do just over 600FSB 1:1 at its stock timings with something like 2.25-2.35v. That is on a Rampage Formula with a E8600 E.S. I don't have the CPU anymore though. I have a x3360. Booo. I don't really bother with 775 these days, I just have it because it was awesome for me in its day. Great board, only problem with it is it snot a DDR3 board. I have some good DDR3.

Enthusiast ddr3 775 boards are hard to come by unfortunately, but with high clocking ddr2 i dont really see a problem since i can theoretically run 760fsb stable with the rams set to 1520, its 775 and not meant to be dailyed unless if its an office pc or ultrabudget gaming pc so over 4gb seems to be pretty pointless imo

 

1200 c5 at those volts is pretty normal for d9gmh/gkx, have you ever tried any higher volts for higher freq/better timings? Cause d9 are supposed to scale well with volt, if you happen to use an asus board you wont be able to kill anything even with max volt incl ram, pretty much the reason why i push 2.46v to my ddr3 rev f stick without it dying cause asus has a safety net

No I mostly just stuck with 1:1 operation. The board and mems were good for 550 1:1 daily with only 2.15v. The NB was at like 1.55v though.. needed to move a little air.

Yea that can be a limiter for really high ram oc, but since d9s usually dont seem to go over 1400 from what ive seen you shouldnt need to increase nb at all or only by a notch or 2, to run 1520 i needed to raise my nb to 1.58v instead of the usual 1.56v i run for ~478 fsb

I think that is where my x3360 tops out at, I can push a little harder but not quite stable. I usually run it at around 4100MHz.

Pretty sure you either have a garbage board or you arent cranking the volt enough, 4100 is acheivable with ~1.3v for most 45nm cpus so your cpu shouldnt have an issue reaching 4.3 even unless you got a garbage board, my p5q is trash for fsb but great ram oc so i dont bother with this thing for cpu oc ofc, for all i know max fsb term 1.5-1.6v, vcore ~1.6v (intel 45nm spec), nb 1.7v (65nm) but you may go higher for larger node nbs, apparently 1.8v pll 45nm but its useless to raise it that much anyways, you actually wanna run 1.3-1.4v for 45nm. With those kind of limits your cpu cooling is prob gonna be the main limiter

 

Whats your mobo?

Its an X48 board, good with 45nm dual cores, but not so great with the quads. I had a 4GHz Q6600 on there before it.

RF is a decent board but when i tested the REX ebb vs maximus ii formula ebb its actually worse than the maximus, i can make a mod bios file with maximus ii formula ebb if you wanna try improving its oc ability, would also be interesting to see the effects of ebb on diff boards cause it could just be the REX ebb is obv not optimized for p45 or it could just be the REX ebb is straight up trash compared to the maximus ii formula ebb

 

Also 4g q6600? That kind of oc iirc requires 1.5v+ so i guess cooling isnt a limitation
