VT7 overclock problems (HELP ME!)
Stats:
Abit VT7
Pentium Celeron 2.2 (400 Mhz fsb)
2 x Geil 512Mb PC3200 (2.5,3,6,3)
2 x Western Digital 80Gb SATA 10,000 rpm Raptors (RAID 0)
1 x 5400 rpm Hard Drive for running Windows XP Pro from
Radeo 7500 64Mb PCI video card
Max Cooler CPU Fan and Heatsink
Raidmax Case w/ 430watt power supply
Here are a few of the road blocks im hitting in my attemps to find the ideal setting of speed and stability when overclocking:
1. When setting my fsb to 130:195:32 (CPU:MEM
CI) my Comp ran bad at stock vcore, and better with each increase until .15 above and then windows wont post or restarts immediatly after it does. But my cpu temp never rises above 30c at +.10 because of my huge fan and heatsink. So if my temps are low, why would it crash at +.15 when it runs at better +.10? Shouldn't it add more stability at +.15?
2. After checking the website for my Geil memory I came to the conclusion that the mobo might be misreading the vdimm voltage. The site suggested a vdimm setting of 2.7-2.8v, with a footnote that all moduels are tested at 3.0v+. So, I bumped the vdimm voltage to 2.7, it runs better. At 2.8 it runs stable as can be but in 2 different benchmark tests my comp ran half as slow and when I put the vdimm at 2.7, back to 2.7 it runs back to speed.
Why would an increase in vdimm voltage impacted the speed of the computer?
3. I can not find the setting for locking the pci/bus. This severly limits the ability for my to use 1mh increments for my fsb setting. After 36mhz im experiencing instability, and after 37mhz My RAID 0 fails because the harddrives dont like the raised setting. PS. Im running windows off of the 5400 rpm drive for assurance, the raid is for my games.
So in conclusion I could use some help.
P.S. I am currently running my fsb at 133:200:33 because a lower fbs means running the pci at an off speed which I believe was complicating the stability problem. Ive have the vcore at 1.62 and the vdimm at 1.70. The Memmory performace features are turned off, and all settings are a SPD. PCI latency is at 150, and all other settings are at "Optimal", for the upgraded BIOS. At current setting Prime95 tourture test errors out with a rounding error after a minute or less, the benchmark runs 15.595-121.345 (awesome). I would really love to stabalize this speed.
