What cpu to get

[clone38]

Not sure what cpu will suit me best,what im looing at are these dual cores.

FX 60

Opteron 170

X2 4800.

Cooling will be done with a mach 2,when i get one.

My motherboard and ram are.

DFI LanParty UT NF4 SLI-D

Mushkin 2GB DDR XP4000 Redline Extreme Performance Dual Channel Kit (2x1GB)

FX60- coldbugged but highest clocking above ambient

DC Opteron- probably coldbugged but does well above ambient

X2- probably not coldbugged performs about the same as the Opteron above ambient

If ya really want phase, go for the X2

I take this meens +temp instead of - temp?

 

[boardy]

FX60 is coldbugged @ -11 so anything lower than that and your not gonna get very good results.

I dunno what Kenny is on about saying the X2 will perform the same as the Opteron tbh the X2 will beat the Opteron hands down.

The X2 is pretty much the safest bet and Mavs even OC'd further than his FX60.

Sorry, from what i`ve seen (mainly on XS) the DC Opterons were doing 2.6-2.8 on water, same as the X2.

Didnt know Mav had got his X2 to 3.4? Sweet!

I`m having one of those days, sorry! :$

I think boardy meant that the gain for the investment if you are on phase right now means the FX60 is not the best choice right now. Bang per buck under phase goes to the x2. But if my tests with a standard non-GT Mach 2 go well, that could all change.

Having said all that a Mach2 GT might run warm enough to get een more from an FX60.

Steer away from the opteron f you want to notch overclocking under phase.

MHO of course.

Mav

Maybe a silly question, but why x2 4800 when the 4400+ exists? likewise, why the opteron 170 over 165?

I realise that as they are rated to be higher then maybe the silicon has more headroom, but that's not necessarily always the case.

 

[maverik-sg1]

It's all about FSB mate - under phase you are unlikely to hit more than 270Mhz before you memcontroller bugs (inherant with a64s) - therefore the higher the multiplier the better your chance of getting massive clock under phase.

The exception being FX cozs the upward multiplier is unlocked.

So Mav are you going to be doing somit special with a FX 60 then m8 ?

ok, i didn't realise that there was a memcontroller bug being a water/air lover. in that case, then yes the 12x would be better. but wow, 12*270 is 3.24Ghz - that really is phase territory! then again, 11x270 is pretty average though too.

Does that problem plague the opterons too as you said a64s?

Depends on memory controller revision, but the CAB2E Opterons were especially bad for coldbug. CABYE and CABNE werent so bad, CABGE is mainly ok and the new KAB3E and 7E are badly bugged as well

 

[clone38]

Mav would it be possable to regass a mach 2 gt to run a FX60 to help stop this coldbug thingy?

I have a FX60 sitting here in the box unoped and would really like to keep it,but if the regass option is not going to work i`ll send it back to the shop and get a X2 4800.

 

[justin]

you can get it regassed to a warmer gas...

 

[clone38]

Ive ask phil about it,the only thing is its going to cost ££ to regass it but would it really help,could still be coldbuged .

Looks like the FXs going back :/

 

[justin]

not if you get a warm gas, it will be above the cold bug (-11) with the new gas. Ask gray...

 

[boardy]

Why would you gas a mach to be a really expensive sorta good cooler? The idea of the mach is to cool sub zero, no point in having it if your gonna stick it around -11 idle

Chilled water probably best bet I would presume, wouldnt you?

 

[boardy]

An FX60 would like chilled water much more than a phase I recon. I was saying it all along that they wud b bugged to high heaven but no1 listened lol. This is what happens you see

 

[clone38]

My mach 2 is on order with phil so i couldnt test it and didnt want to, if like everybody says there is a coldbug issue,going to order a X2 4800 and take it to ice heaven

Wrong on the X2!!!

You are absolutely wrong on the X2 not being cold bugged. I do have a 4200 X2, forgot the stepping, that isnt cold bugged. Baught a 4800 x2 hoping to use the 12 multi. Well It is severly coldbugged. will not run over 240HTT(CCB2E 0536). I have read more about the opteron 170 not being coldbugged. I would think the FX-60 could handle it if you use the Multi to clock,leave ram @ stock.
