That was ref RAM voltages.
Sorry,from ages back I know ,but have you got a link I could check out regarding safe voltages for Crucials std DDR400 RAM?.
Btw benchmarking doesn't tell you if the voltage given to RAM is safe in the long run (2-3yrs +) :p
In the meantime I'll stick to my rule of thumb of max 10% overvolt for CPU & RAM ;)

If that runs the blend test in prime then that's damn impressive compared to mine. :)

If the 'blend' test is the first of the three to fail, in my experience it usually indicates that the memory or motherboard, rather than the CPU, is topping out.

Have you tried running lower memory/CPU multipliers to test the limits of the memory and motherboard?

BH-5 vs TCCD

Well finally cracked 23m with winbond BH-5 ram and still have room to move :D As you can see from the times BH-5 was +20mhz faster equivalent at same clocks as TCCD i.e. 3102mhz BH-5 = 3120mhz TCCD

2x 512MB Corsair XMS3500C2v1.1 BH-5 on 166mhz divider

Super Pi 32M
@3000mhz at 1.44v = 24m 00.719s
@3102mhz at 1.536v = 23m 14.906s
@3120mhz at 1.536v = 23m 05.171s
@3141mhz at 1.568v = 22m 59.453s
@3150mhz at 1.616v = 22m 56.875s

vs

2x 512MB Gskill PC4400LE TCCD on 180mhz divider

Super Pi 32M

@3102mhz at 1.536v = 23m 23.735s
@3120mhz at 1.568v = 23m 14.547s
@3130mhz at 1.568v = 23m 10.297s
@3133mhz at 1.568v = 23m 08.500s
@3141mhz at 1.584v = 23m 05.891s
@3150mhz at 1.616v = 23m 03.531s
 
Very strange - been having problems getting this thing stable at 2.8 and above.

Volts are 1.5 at the moment, HTT 280x10 and its been stable all night (15 hours).

Only thing I've changed is I've removed one of my Corsair XMS 3200 C2 sticks that were running in DC. They're not actually part of a twin kit but I'm confident they're pretty much identical.

Is this my problem though? Am I trying to run two disimilar sticks of ram in DC?
 
wouldnt of thought so, i remember having 2x512mb running in dual channel on my p4, 1 was a stick of samsung, the other was twinmos, even the cl wasnt the same, 2.5 & 2.0 but worked a treat in DC

I've got two sticks of Corsair XMS3200C2PT both 512mb each, one stick is v3.2 and the other is v4.2 they wont run dual channel at all, more chance of me meeting daffy duck I think than them running DC :(

Yeah if one stick is bh6 or something, and the other is tccd (just plucked those from the air, not sure if corsair used those) then would imagine it'd act up. Try running them together in single channel......

If you have nothing constructive to say, why the hell did you post that?

Sorry I ruined you little joke.

Instead of trying (and failing) to be witty, find something that will actually help people with this problem.

lol, that's incredible... did you get the joke? It was a little light hearted and harmless fine, calm down.
 
eva2000 can you put your LE at 300FSB (tight timings say, 2.5-4-3-7) with no divider please, so 300*10 and compare this against BH5 running 300FSB with a divider as you have done previously. To be fair, TCCD shouldn't be used with a divider since it does such high FSBs with tight timings.
