2.85v and 3.15v.. no diff?

[jagare]

I just got done volt-modding my P4C800, now I have 3.15v running through the RAM. I can't crank the FSB up any higher though in 1:1. My prior stability wall before at 2.85v was 265MHz FSB. Now with 3.15v I can't get it any higher then that, any idea why that is? I have OCZ PC4000 Gold RAM and I'm running the 1010 bios.

Could be that your chip has incidentally hit it's limit?

I can run 285mhz FSB 5:4 stable. So I know its not the CPU.

You know it's funny to see this thread because I have the exact same problem. My OCZ PC4000 EL is stable at 265 1/1, but it won't go any higher without losing stability. I have the same motherboard and am maxed at 2.85V. I know my max fsb is 285-290. I was hoping a Vmod would help me push the memory higher, but it doesn't look like that's going to work. I wonder if anybody else has the same problem?

[jagare]

I was told that I might need to 'burn-in' my RAM and that OCZ PC4000 Gold requires it sometimes to run at higher FSBs' at 1:1. I wonder if thats true.

Thats how all RAM works.

At first mine would only do 220 2.5-3-3-7 @ 2.85v. After heavy usage for a few days they did 223 2-2-2-5 @ the same 2.85v.

Some sticks just don't like higher voltages either. 2.9 or 3.2, some of them will still perform the same.

Yea, mine doesn't really like to go above 267 1:1 at crap timings without errors. I'm geussing I might be able to get a bit higher, but I'd rather not have to reinstall windows. (thats at 2.8v)

my corsair pc2700 maxs at 182 with 2-2-2-6 times and a 2.7 volts. i tried 183 with 2.9 volts and my system wouldnt even post. the burn in thing does work. my max used to be 175 and i had it there for a couple months until i got board, then BAM... 182. i probly didnt have to wait that long though as soulburner only waited a couple days. just run memtest in your spare time for about a week, then try again. im sure that will help

[Clevor]

Yep, same here. The OCZ PC4000 Golds I tried maxed out at 260, 1:1, and more volts didn't help. And these were SS sticks on an Epox 4PCA3+ board, which has VDIMM to 3.32!

With the same board and CPU, I've gotten SS ADATA PC4000 up to 282, 1:1 at 2.9 VDIMM. Both brands are supposed to be using Hynix 4.0 ns chips.

Whats the highest vdimm i can run for mushkin pc3500 ram for daily use

[jagare]

I would say 3.1 maybe 3.2. Does your vdimm work correctly over 2.8v with the Max3?
