My cousin received his E4 3200+ s939 Venice a few days ago and we overclocked it yesterday. His case has about four case fans, and we used the stock AMD hs/fan.
Antec TruepowerII 380W
AMD Athlon 64 Venice 3200+ socket 939
BIOSTAR TForce6100-939 microATX
1GB Geil ValueRAM
First of all, the BIOS is amazing for a microATX! I wish I had those kinds of options .. vcore, vdimm, memory clock (i.e. 200, 166, 133, etc.), HTT, LDT (no chipset voltage though), CPU multiplier, built-in memtest86+!
; basically the works. The only important thing that it was missing was the chipset voltage, I think.
So we lowered the LDT to x4, left the multiplier at x10 and started raising the HTT on stock voltage (1.35v). Everything went fine, and idle temp stayed at 30*C, but I noticed that CPU-Z reported 1.317 or so for voltage. How accurate is CPU-Z's vcore reading? Anyway, when we got to about 240, we started getting BSoD's after the Windows loading screen. So I raised vcore to 1.375 and then 1.4 but the BIOS reported that the CPU was unstable. I thought that was strange, so I raised vcore to 1.425 and it still didn't work.
At that point I began to wonder about the mobo's voltage supply. If CPU-Z was correct, the board was undervolting at stock, so who knew what it was doing when we raised the voltage? In short, we never got the computer to boot with anything but 1.35 on the vcore. But the computer appeared to be stable at the board's undervolted stock voltage, so we lowered the memory clock to 166 (the Geils tightened up their timings automatically - dunno if this is common) and returned vcore to 1.35 and whaddaya know? it worked. So we continued on, lowering the LDT to x3 when we reached HTT 250, but we couldn't make it to 260 (FX-55 speed right???).
I forget exactly what the stepping was, but it was a week 43, i believe. However, we ordered the CPU soon after the E4 arrived at newegg, so hopefully it's a good one. I think with a proper overclocking motherboard that can deliver higher voltage, this baby could fly, since it made 250 on stock (or maybe even less?) voltage with the regular hs/fan and paste.
Unless we did something wrong?
