I just tested my good ram (PC2-9136) with my bad ram (PC2-8500). The bad ram can't even do stock of 1066MHz 5-5-5-15 W/ 2.2v (stock in 2.1v). But I put the two kits together and they do 1066MHz 5-5-5-15 W/ only 2.04v.



WTF

I read that the more stick the harder it is to run at a speed. Therefore needing more volts. But I got way way less volts.

Anyway could someone explain, I must have misread.

What stick do you have in the 1st slot? If it's one of your good clocking ram sticks, it may have something to do with the SPD of that kit, as all 4 ram slots settings are set by the SPD of the stick in the 1st slot, other than the settings you have set in bios.

It doesn't take more vdimm to run 4 sticks as opposed to 2 (unless the ram you add needs more vdimm for the same clocks as the ram already in the board), but it will take more vNB as it's harder on the MCH.

I have my good PC2-9136 in the first slot. Also all the BIOS are exactly the same. I must have misread that u needed to up the vNB, not the vdimm - my bad. BTW my vNB is exactly the same as with only 2 bad sticks. Anyway i'm happy

Check the SPD of the dodgey sticks that wont run stock. I have seen some very weird Corsair SPD's, like 0-5-5-15 (that was on a set I owned) and other equally stupid settings. I don't know why they don't have better QC concerning this but they have a bit of a rep for bad/inappropriate SPD settings.

I have had and seen other have numerous bad experiences with Corsair ram, IMO the only decent Corsair sticks are the PC-10000 kit, and even then it only really does CL 4 well, it's hopeless at high speed CL 5, like all Corsair ram. However when you factor in the price, none of their ram is worth using, as many other brands do better and cost significantly less.

Come to think of it, one of my OCZ Reapers has a funky SPD, tried flashing it with SPD-Z but no dice.

I checked the SPD and its all ok. My PC2-9136's suck at anything but CL5. Even 2.5v doesn't get me 800MHz 3-3-3-9 . My dead PC2-8500 were better at low timings.

[fatguy1992]

I got my 4GB of ram to 1200MHz 5-5-5-15 W/ 2.1v, almost stable, one little increase would do it . Anyway, with my good kit (PC2-9136) I couldn't even get 1200MHz to post W/ 2.3v+, yet alone even windows and bench ok. WTF I add my crap sticks and I have u use over 0.2v less. I could understand if it was the same volts, but 0.2v less is quite a bit. I don't get it, neither kit ny itself can do it, so y can they when they are together. BTW The BIOS settings are 100% the same.

[CryptiK]

Woah, you can't do 400 CL3 at 2.5v or 600 CL5 at 2.3v? You'd assume if it was very bad at low CL it would be good at high CL, but that is not good at either. That's not very good for D9 at all mate. How much did those sticks cost you?

When you get your Team & Cellshock, you will want to throw those Corsair sticks in the bin.

[fatguy1992]

I paid $175 for them but they were half price and my other stick had died and I didn't have time to import Cellshocks etc. So I got them. They did do 1333MHz 5-5-4-15 W/ 2.58v. I know its not that great.

I'm going to run both kits at 1066MHz 5-5-5-15 W/ 2.03v for 24/7 and the Cellshocks are for benching and overclocking

I'm soooooooo looking forward to my Cellshocks

Ok im running 4x1 xtreem team 1300s on gigabyte ep45-ds3r with a e8500. I have been playing with running my memory around 1300, processor at around 3.8, i have no problem getting there, but i cannot get rid of the errors in memtest86 test number 5, have tried everything just wont go away. I was thinking it was just to much speed on the ram, i have about a 480 fsb on the 400 strap, so i decided to try something i lowered the fsb to 410 on the 400 strap using higher multiplyer so i was running my ram at 1339 ,with a fsb of 401, and ran memtest again, passed no problem like 5 passes. So my question is what do you think is causing the memory errors ? are the errors only affected by timings ? or is it a combanation of all things ?

Ok another thing is when i take 2 sticks out, and just leave 2 in, on the same settings 480fsb i can pass memtest no problems, so am i to asume my board dont like 4x1 ?. thanks for your help.

[Shiranui Gen-An]

Did you try bumping up your northbridge voltage when running 4x1GB at 1300+?

[CryptiK]

Also, what divider were you on when you were running 1339? If it was the 3:5 divider on the 400 strap, it was not really at 1339. But yes, as said above, based on the fact you can run 2 sticks at the same settings error free, it sounds like your NB is the cause of the problems. However test both sets of sticks, one set may be not able to run that speed, but if both kits can do it alone, and not when running 4 x 1, it's your NB.

[neo mike]

Ok my northbridge voltage is 1.59 which should be enough ?. I was running the 333.d divider when all 4 sticks passed at 1337. Cpuz reports the samething for memory speed on the 400 strap as the bios, so cpuz is wrong ?.


I know all 4 sticks are good cause it passes at 1337 with 410 , 401 fsb with the 333d divider. I will try to increase the northbridge voltage and see if that gets rid of the errors.. I have tried the 333 strap, but that strap only lets me get high memory speed with no fsb, or high fsb no memory speed. I will report back going to run memtest again with more nb v. Thanks guys.

SPD-Z sucks donkey balls, use SPDTOOL Best thing to do would be to take a spd dump from the good stick and put it on the "bad" stick using SPDTOOL.

Ok well now im on the 266 strap 500fsb 1250 on the memory 5-5-4-12 and it passes memtest86 no problem. Im getting 10,000 in everest, and 51.7 latency, thats a little high trying lowering my trfc. Just dont seem that fast, i would really like to be around 1300 on the memory, or i feel i got robbed on these sticks, i could have gotten sticks half the price of these that would put me where i am now. Well at least im stable and no errors , will try to push em more see what happens, thanks guys for all your help

[Ket]

NP On a totally unrelated note, I need a pee

your board wont let you go higher in everest
with dfi ut p35 you would see 11k+ @ those speeds
and with memory @ 1300 i get 12k in everest

[neo mike]

So your saying there is no way i can pull 11k in everest with my board ? and why is that ? i have gotten as high as 10,800, im thinking of maybe getting a x38 or x48 board. So why wont my score go up, but it would on a p35 at same speeds ?

its tough on gigabut boards you get high clocks but performance suks
run @ higher fsb if you want more
n lower trfc try doin 1220-1250 trfc 28-34 500fsb+ +pl 7-8 333 or 266 divider
btw its not how high you clock memory its finding the sweetspot for 24/7
why bother with x38-48 unless you need 2x16 pci-e
i boxed my x38 caue it didnt like my e8600+ my utp35 if faster

[Shiranui Gen-An]

I'd be glad to take that X38 off your hands

[neo mike]

Thats what im looking for is the sweet spot, i am on the 266 strap, trying to tighten up my timinings.

[neo mike]

Well zsamz i left my fsb and timings and everything the same, and just switched over to the 333 strap, i dont see any difference, of course fsb, processor are running same, but memory speed 50mhz less, barely broke 10,000, so i think im about good as a GIGABUT board will do, i find hard to believe that if i was on a p35 dfi, my performance would be that much better, maybe so.

[zsamz_]

long line
i keepin it as my backup

even the dfi ut p45 is as fast as the ut p35
i'm happy i'm off that gigabut boat

[Ket]

DFI are NOT god. There are plenty of other boards that are far easier to get on with (note: much more stable and reliable) and offer performance that is not exactly off the pace with a DFI. I will never touch a DFI board ever again after the NF2 and NF4 hassles I had with DFI boards, POS wasn't even stable with stock settings. Throw the exact same hardware on any other manufacturers board though and no problems. Can't comment on a Gigabyte board as the last one I had used a VIA KT400 chipset However I can vouch for Asus P45 boards (currently I got 9.5GB\s bandwidth with a measly 3.2GHz @ x8 400FSB) TPower, in spite of its horrible BIOS, and even the MSI P45 boards.

Can any one tell me which is likely to be best out of either CellShock PC2 8000 CAS4 (GKX) or Cellshock PC2 8500 Cas5 (GMH) looking at running 4x1GB DIMMS on my P5Q deluxe
