Asus sli-premium oc help!

[bennny]

Hey,
I have a asus sli-premium with 1 gig of hyper x 2-2-2-5 @ 2-3-3-10, with a amd64 winchester @ 2240mhz, fsb currently at 224. 1.4 volt for cpu and 2.6volt for ram. 500 watt thermaltake ps. I can not move my fsb any higher, without crashing my computer. I am using ai booster to push the fsb up, and it worked till 224, but cant go past this mark. Is there a way to increase the multiplier? In the bios it is stuck at 10. I have tried many different ram timings, and ht multipliers. Currently im on a multiplier of 4 for ht, and in the bios, the asus bios is kinda wierd, never seen one like this, but, it says my ram speed is set to 400mhz, and i can change that around too. On 2t timings, and have tried 1t timings with different ram timings and lost stability. Any help on suggestions to push it farther would be good. O, and I think the cooling fan is like a copper thermaltake venus 12 or something to taht effect. THANKs!

You would want to decrease the multiplier since the 3200+ 939s are 4-10 multis only. From 8 or 9 multi, you need to start your OC. Did you make sure CnQ was turned off? Oh yeah, it would also be better if you did the OCing from the BIOS, not some software prog. BTW, Thermaltake PSUs are crappy for OCing. I have a 470W myself and it can barely handle the OC I achieved with a Cooler Master RealPower 450W.

You cannot raise the CPU multiplier above the stock multiplier. That feature is reserved for AMD FX chips only.

I can explain the odd RAM multiplier lingo for you though. The Memclock Index is ASUS' way of saying RAM Multiplier. When they show DDR400 it means 1:1 with CPU HTT frequency. So if you have the Memclock Index set at DDR400 and the CPU HTT at 224MHz, then the memory is running at DDR424. If you want to lower down to say a 5:6 ration, select DDR333. And so on down the line.

You should be able to run with a Command Rate of 1T with only 2 sticks of DDR installed, and that'll boost your bandwidth by a good margin. Try that. Also, try lowering your Memclock Index down to DDR333. You may eventually be able to run the the CPU HTT at 250MHz with the CPU multiplier at 10x for a 2.5GHz CPU speed. With the Memclock Index at DDR333, your RAM will only be running at 208MHz, most quality RAM sticks can run at that speed or beyond. But you should work your way up, don't go for the gusto right away. Be thorough and methodical about it. I spent weeks tweaking/tuning/abusing/testing my own machine. It was fun for me yet safe for my ungoldy expensive parts.

You may be able to run with low or stock Vcore, but you'll likely have to boost it up some as that is a 500MHz o/c. But you should be able to keep your Vdimm low, probably at stock. You should not have to bump chipset and HTT voltages at all.

If I think of anything else, I'll post it up. Good luck and have fun.

Hey thanks for the advice guys, keep it coming if you have anything else.

You have to give it more juice otherwise you aint getting any higher .. VCore of 1.55V is safe for sure ... upto 1.65V will probably be fine but you're better of keeping it below 1.6V just to make sure.
