Overclocking my FX-55 to full potential

[Dirty_Harry2]

Guys I have overclocked my FX-55 to 2.9 gh, I want more. I have been told that the max is 3.7 gh from this thing. I'll be honest, I would like to get it there. Help.

Are you still running the stock heatsink and fan? What's the spec on the rest of your system?

 

[godman]

3ghz is usually with water, any higher you'd probably want a chiller or go phase =]

Have a look at reducing latencies for you ram, small tweaks etc?

FX-55s Oooo! I remember when they were the king

 

[Dirty_Harry2]

No I have a much better heatsink and fan, gigabyte something or other, at 2.9 under load I am at 114 degrees. That is the max. I do not know how to tweek the ram at all. my system:

Manufacturer: Self
Processor: AMD Athlon(tm) 64 FX-55 Processor, MMX, 3DNow, ~2.6GHz
Memory: 2048MB RAM Corsair XMS
Hard Drive: 160 GB
Video Card: ATI Radeon HD 2900 XT
Monitor: Samsung 204B
Sound Card: Plantronics Headset
Speakers/Headphones:
Keyboard: Logitech G15
Mouse: Logitech G5
Mouse Surface:
Operating System: Windows XP Professional (5.1, Build 2600) Service Pack 2 (2600.xpsp_sp2_gdr.070227-2254)

Yeah, I mean, that's as far you'll be able to go...

I have no idea how hot 114f is in celcicus (I live in England though lol)

You've almost hit the peak performance without changing motherboard and processor, as I said, unless you want to get better cooling =]

Nice system btw 🙂

Your rig getting unstable above 2.9?At what is your HT running at that speed?You can raise the FSB on your MB but then you'd also have to lower your HT multiplier to keep it at around 1000Mhz. My 4000+ is running at 2.8 Ghz with 2-3-2-6 1T timings on my Corsair CMX1024-3500LLPRO's.

 

[Dirty_Harry2]

No, it is not getting unstable. I just don't know how to bump it any farther. I did the AI overclock in the bios, but I don't know how to go any further.

 

[cfvh600]

You'll have to manually adjust your FSB speed and HT link settings if you want to go above 2.9Ghz.Might also have to adjust your CPU voltage.

 

[Dirty_Harry2]

Sry, dumb question, where do I go to do that?

 

[cfvh600]

It would probably be under the same menu where you adjusted the AI clock I think, have to choose the "manual" option somewhere.What mobo do you have?The manual will probably help you out if you're unsure where to get the options.

 

[Dirty_Harry2]

I have an Asus Sli premium, I know I used to have Nvidia cards.

I thought the FX55s Multiplier was also unlocked as the other FXs are, simply set the CMOS settings to manual instead of the AI, and increase the multiplier,,, 2.6 is a 13X multi, 2.8 is a 14X, 3.0 si a 15X, Etc.

You'll have to increase the V-Core to run higher multipliers, but everything else stays in spec, make sure you have good cooling!!!

Watch the V-Core carefully as ASUS M/Bs run those voltages higher from the git go, you should be able to hit a 15X multiplier around 1.4v, but use that information to sneak up to where you want to go, don't try to go straight there.

You probably won't get past 3.0GHZ on air, you have to keep it cool, thats the most important thing!!!

I had my FX57 @ 3200MHZ on water but when I went back to air couldn't stably run a 16X multi on air, my FX60 is essentially 2 FX55s, and on air I have them running a 15X Multi @ 3.0GHZ using 1.4V V-Core.

I've obtained and FX-55 on an ASUS ____ mainboard ... during boot, the BIOS reports 5819 MHZ CPU Speed!

It's running Windows 7 and, apperantly, very good grade of RAM (2GB) ... seems impossible and odd all at the same time! ... had a 256 MB XFX video card on it ... couple of IDE HDD's
