FX-55 OCing

So yea, I picked up an ultra cheap FX-55 from NewEgg for $139 shipped. Upon arrival, it had a stepping of CABCE 0520MPM (which I have seen on FX-57 cores.) Seems to be a pretty good overclocking stepping/batch.

I cranked it up on the stock multiplier up till 3GHz (231HTT x 13x).

I lowered the multiplier and I'm now going to go high FSB. I just left it on memtest windows overnight (actually, I fell asleep LMAO.) So gonna increase it some more.

It's at 310HTT x 10x multiplier at 1.5v and it has more to give.

I might have to increase the multiplier to 11x soon coz I don't know when I will hit the FSB limit of the board. Gonna increase it some more.

Cooling is done on my modded Corsair Nautilus 500.

Will keep you guys posted.... Gonna spend my weekend pushing this baby to the max!

 

wow, that's a good price..
where do u stay?

& how the heck did u manage to pick steppings n batch fr newegg???

 

3.1GHz 1.5V, damn that's nice! Slightly better than my wonder Opty 144

 

I'm at the US of A...

You can't pick steppings. I just got lucky and got one.

It doesn't seem to like most of my ram timings though. Maybe a different controller?

Gotta redo ALL the ram timings... :\ BAH! more research....

 

ic..

my opty146 can do 3ghz @ 1.5v easily...

got any benchmark screenshots for viewing pleasure?

 

Sure.

Lemme take a few.

I'm at 3GHz @ 1.5v right now with this ram (6hour prime stable - will most prolly be my 24/7 setup.) I had it prime (4 hours) at 3.1GHz @ 1.5v but haven't tried higher. Wanna keep my ram maxed out as much as possible (for the bandwith.) But trying to push a bit more. I've had this ram stable at 260MHz 2-2-2-5 but the 3.5v kinda scares me... 3.3v right now.

 

no bad...
my opty146 kinda max out @ 2.97ghz prime 8hrs stable..

3.5v.. is that a pair of BH-5?

 

UTTs...

CH-5s.

Will post some benchies soon. Stay tuned!

 

Here's some quick benchies.


A64 FX-55 @ 3.0GHz @ ~1.5v cooled by modded Corsair Nautilus 500 - copper radiator, Delta 120mm 190CFM
DFI NF4 SLI-DR
OCZ Gold VX PC3200 @ 500MHz 2-2-2-5 @ 3.3v
XFX 7900GT *stock* 520/1500
Hitachi Deskstar 160GB SATA3.0GB (NCQ disabled)

My 3dmark05 was a bit low. Wonder why..

 

Here's one for you to beat
Done on a very cold night many months ago.
Shouldn't be too hard with your RAM speeds...I wasn't using the >3.2VDIMM jumper on mine.

 

u gonna o/c ur 79GT? give u sth useful:
http://sg.vr-zone.com/?i=3437

show u mine ;P

 

Yea I'll do some suicide runs later. Still trying to find my 24/7 stable speeds with my Delta on 7v. After that.... 190CFM on my radiator and 3.5v on the ram...

 

well.. but then it isnt 100% stable...
most stable setting is 2.97Ghz with ram running low @ DDR540

 

"suicide runs", lol...
will be looking forward for ur result!!

surely ur DFI mobo can clock much better than my Fata1lty nF4-Ultra

 

huh?
wad was ur specs n result then?

 

*cough* get an FX-55 and don't leave too much to luck...

 

ic... u shld study XS's database n pick the batch which has the most o/c potential..

my 3500+clawhammer reaches 2.65ghz
my 3500+venice reaches 2.75ghz
my current opty146 venus reaches 2.97ghz.. quite satisifed with the result.. but not the price
