Hi all,
I have recently ditched my X2+4400 AMD system to return to Intel once again ( - sound of drums and general pandemonium amongst the crowd - ).
So I picked the Asus Rampage Formula (want to stick with DDR2 for a while still) and a Duo E8400 (stock clocked at 3.0GHz ) to go along. Also, I was fed up with the 4x512 OCZ setup (although they were excellent) taking up all slots and went for a cheap 2x2Gb Corsair PC6400 alternative which clocks nicely at 333MHz with 4-4-4-12 timings
Only drawback is that since I run WinXP SP3 I can only see 3.3 of the 4Gb.
The rig right now is set to FSB:333, Bus to Northbridge:333, DRAM:667 and as such CPUZ correctly reports a strap of 1333. Core uses 1.2V at 3GHz and RAM shows a use of 1.9V which is well within the manufacturers range of 1.8V-2.1V (CPUZ confirms). Both voltages are set to auto in the BIOS.
Realtemp reports Idle temps of 38-40C for the CPU . After 3 mins of Orthos the temp rises to 60C at which point I stop it. Need to get myself an Ultra120 HS before doing any more stressing it seems although I did run several 3Dmark06 sessions without problem scoring 12,700 with the 9800GT at stock and 13,300 at maximum stable OC (with rivatuner). From what I gathered these are good scores for an unOCed rig.
And this brings me to our problem:
Last night I tried to push it up a bit and set it to FSB:400,Bus to NB:400,DRAM:800. Now, Corsair says that this RAM needs 2.1V to run at 400MHz so I manually set the BIOS voltage setting for DRAM at 2.08V (heard this MB overvolts by ~0.02). I also bumped the CPU from auto (CPUZ reported it using 1.2V - HWmonitor also 1.2V although it recorded a 1.18V low) to 1.25V. I Post successfully and notice the idle temp for CPU has only risen by 5C. But the NB is going crazy at 55C idle instead of the usual 40C! Now I know Asus has done a really bad job at setting those NB/SB heatsinks (thermal pads and other atrocities) but I had no idea a 66MHz bump on the NB would cause it to rise by 15C! Needless to say I set the alarm stage to BROWN and rebooted switching all settings back to the 333 FSB setup (including voltages to auto).
But now I get random BSODs....if it wasn't for Firefox's restore session function I would have had to retype most of the above
Temps are all normal (low) but what I have noticed is that HWmonitor reports some crazy voltage spikes! For some reason though the parameters one sees on my HWmonitor are not straight-forwardly named so it's hard to understand what is what. For example the +3.3,+5+,+12V rails are obvious as well as Vcore. But the rest of the values are named VIN1,VIN2,VIN3 and so on. These have what seem like normal values ranging from 1 to 3V. What is strange is that the MAX recorded value for all of these seems to be 4.08V! Now if I'm not mistaken that's quite a spike!
I'm using an Enermax 500W Liberty hooked to an APC 800W UPS so power is as clean as amateur money can get. The PowerChute app reports that the UPS provides 233W and that includes my 32'' Samsung LCD I use as display so that's well within it's limit!
Would someone be so kind as to help me stabilize my system at stock clocks? I really would like to have a go at OCing this rig as this board is asking for it!
