Are you at 3.2 right now testing prime?.I think you need new sticks of ram.Even Corsair didn't recommend your sticks in the 3200LL

[Thor]

Yeah, testing at 3.2ghz 266 fsb, 1.6vcore. Prime95, two instances running with Hyper Threading, so far at 9 hours solid, no errors.

My ram is Corsair TwinX3200LLs, and yeah they suck for systems with high fsbs. Oh well, will be getting better ram when they are out. :beat:

[Thor]

Well, looks like the 266fsb is the limit for this 2.4 and P4P800 I've got setup. I will try and use 1 stick of memory and maybe even disable HyperThreading to see if it will go higher.

Then it's 2.6 time! :rock: :rotflmao:

[oldfart]

I would think that 3200LL should be able to do 5:4. Thats only DDR426. My 3200C2 non LL can.

[Thor]

Yep, 5:4 no problems.

Testing my 2.6 now, and it's humming along at 250fsb 5:4 1.575vcore.

Where is the limit for it? My XMS 3200C2 (not LL) poops out right around DDR426 2.5-3-3-7 @ 2.8 Vdimm. Whats interesting is it can do DDR 412 2-2-2-5 @ 2.8 VDimm. Seems to :beat: rather abruptly. This is on the IC7 board and the 845PE I had before it. I would think the 3200 LL would be a little better.

[ErikaeanLogic]

my XMS3200C2 non-LL does DDR424 at 2-2-2-6 (so far, haven't heavily benched it higher) but it takes the whole 2.85Vdimm to do it. I think that's odd, since it can do DDR400 at 2.5V.:confused: Just lucky, I guess:).

I think my TwinX3200LLs can do 440 at 2.5-3-3-7 @ 2.75 VDimm max. But let me double check on that when I get my 2.4 back in my system and start tweaking. ;)

[ErikaeanLogic]

wow! my XMS is now cooking along at DDR448 at 2-3-3-7:look: !

how the heck did that happen??:scratch:

[Thor]

That's some "hot" ram, no pun intended. :-)

My TwinX3200LLs are running 427 @ 2-3-2-6 @ 2.75VDimm :eek:

2.4 testing updated!

[Thor]

267fsb seems stable so far, testing continuing.

[ThugsRook]

go Thor go!

:wave:

[pastorjay]

Looking good!!! :yummy:

PJ

[Mikki]

Very nice Thor!!! :beer: :rock:

[Thor]

Hehe.

Thanks everyone!

Just played couple of hours of CS without any hiccups. Going to Prime95 overnight and 24+ hours to see if it's solid as a rock.

:D

[Thor]

Updated, testing for 268fsb at 5:4 memory ratio.

This new bios and a 60mm P1 cpu fan ziptied to my MCH is working better. :D :D :D

[LastRide]

My 2.4C is only at 3.5GHz default voltage:D..LOL.The OCZ PC3700 Gold kicks @ass.

[Thor]

Well, 266fsb seems to still be the limit with this board and/or cpu, but I've got a Zalman fan bracket and a 120mm Panaflo H1A on the way, so maybe can reach 270fsb with active cooling over the board. At least my vid card will be able to be cooler as well. :D

[anvil]

Last Ride,

Is that 5:4 or 3:2?

anvil

[LastRide]

5:4
