Overclocking question!

[markkleb]

hey Tox, if you fry ur CPU can I have the 8800

I would raise the clocks with stock Voltage, than bump the volts a little and keep going. The lowest Volts that runs 2.5Mhz is a good OC for your comp.(try to stay around 1.4 to 1.45)

There are probably people that can get it over 3Ghz but because they are really insane OCers. I saw a Sandi 3700+ (stock 2.2Ghz) that got to 3.7Ghz before it melted down.

If I was you I would enjoy my 8800 a while before I toasted my comp.

It was completely fine under air at 1.57. Of course your not supposed to do that, but thats what being an OCer is all about. Which of course why im not one anymore

that poor chip!!

If you have a monitor to check your HTT (Hypertransport), make sure it isn't through the roof. I got stuck at 2.5GHz with a 2.0 Opteron, found that if I dropped the HT from 1GHz to 800MHz I could go further with my cpu. Apparently the HTT rises with the cpu/ram, so you may hit a wall with it in your overclocking adventures.

(I haven't tried to do any oc'ing with AMD for some time now, so I'm not entirely up to speed on the nuances of AMD procs right now.)

You can always watercool, peltier or phase change, too.

I have the HTT at auto.. So its the FSB x auto??! = HTT!

 

[FarFarAway]

Well with AMD yo have an onboard memory controller that runs at the FSB (called HTT in AMD's) x 5 (except for socket 754).

Then the memory runs at double that of the HTT.

To get the processor multi you use change the HTT multi (which is set to whatever the speed of the proccy 0 e/g. a 3200+ Venice is 2.0ghz so HTT multi is 10x)

You should lower the memory controller multi (often called the LDT bus) for better results

Please take a long hard look at the stickies in the AMD section

With u`r results, some1 else on this forum and another rumour mounger - 2.7/2.75 seems to be the stable area as a concensus. Wc that is. Air can be anything to 0.4 lower at sub 65 deg temps.

well i personaly like to keep my cpu at or under 1.5v on air... im running 1.45 with the opty 170 @ 3ghz... you need to keep track of 3 things and you can get oc...

keep your HTT at or around 1000mhz, its better to be under than over in most cases because of stability

find the max your ram can go and try to keep it around that

then find your max CPU speed... dont go over 1.55v's on air IMO

try to find a place were your comferable keeping it running at all times... my chip can go to 3.2ghz @ 1.55v's but i run it at 3.0 @ 1.45 cuz thats were i like it best

youve probly herd all of what i said before... w/e hopefully it helps

anyone can correct me if i said something wrong/ or mixed my words up, but what i said works for me
