Finally made it to 2.7ghz

[Gig-O-Ram]

Well, today has been an interesting day for my CPU. I wanted to try to increase my overclock from 2.65ghz, and after messing with the system for over an hour, I think I made it.

I started this morning by taking a 265HTT to a x10.5 instead of the x10 I usually use, which was going to give me a 2.72ghz OC. When I rebooted, nothing happened, and I couldn't even get back into BIOS. So after clearing CMOS, I tried upping the vcore a little bit (to 1.43 I think) and set the FSB back at 265 x10.5. Again, nothing happened and I had to clear CMOS again.

I got some advice to the effect of raising the vcore to something close to 1.5v or 1.55v, and I set the HTT to 270 x10, the RAM to CPU/14 (150) to get my new OC of 2.7ghz, with the memory @192.3Mhz - which has been going all day through a few hours of gaming and even a couple hours of stress testing on Prime95. The CPU is on 1.45v and the vcore is on 1.53v. The CPU temps during the Prime run never went over 42°C. In fact, even idling, the CPU temp only went up a couple of degrees from what it is on stock speed. I think I might be able to get to 2.8ghz with the vcore set like it is, and I still don't seem to need to change the RAM timings either.

hey if you want i can give you my settings i used for my 3700. to kinda give you an idea what i needed for 2.8ghz just lemme know, ill go jump into my bios real quick and post it for ya :)

OK, that sounds good. I haven't yet tried going higher, so I'll see if I can match what you did. But from what I can tell, there is no problem with the 2.7ghz. I may go to 2.75ghz before I try 2.8 though, just to see how IT works.

congrats! It's always so rewarding hitting those personal milestones!

Gratz man. Looks like it's to update your sig.

Congrats , but psh i can reach 1.5Ghz from 1.4 :P

My system can't even get past 2.3. It's so dissapointing.

When my A64 3000+ was alive, i got 2.3 Stable and 2.4 Scren Shot/CPU-Z stable

ok so heres what i got:

CPU:
FSB Frequency : 255mhz
LDT/FSB Ratio : 3x
LDT Transfere width : 16 down 16 up
Pci Express Frequency : 100
K8 cool n' quiet : Disable
CPU vid start up value : startup
CPU vid control : 1.475v
CPU vid special control : above vid 110%
LDT voltage control : 1.30v
Chipset Voltage control : 1.6v

Memory
DRam voltage Contol : 3.2v
DRam frequency set : 166(5/06 divider)
command per clock : Auto
Cas latency control : 2
Ras# to cas# delay : 2
Min ras# active time : 8
row precharge time : 2
everything else below is how it was set at default

now with 1.475 + 110% that will give 1.59v in the bios to the cpu so you may want to change that to your liking or what your chip can handle

i know that the ram it totally different so your going to have to adjust it to your specific ram, i just posted mine just to give you an idea of what i did and didnt do with my memory

I think you guys are pushing a little too much voltage....just my opinion....but 24/7 I wouldn't go much past 1.5V. I also think the best O/C is the one you can get the best ratio from (What I mean is by all means O/C, but when you hit a wall and going any further requires a big boost in voltage....stop).
