Mines a 408 aswell. Doesnt like too many volts, lots of people over at XS are reporting this aswell. I have pushed her to 2.9ghz already. BTW, watch your PWMIC temps go sky high when you get to 2.9ghz+...screenshot to follow @ 2.9ghz

im v close to ordering one of these puppies!!

Do it, but if you dont like noise then stay far, far away. It moves so much damned air though its nutz!

Impressive!

I've noticed my chip doesn't like too many volts at all. I think i'll keep her below the 1.45v mark to make sure i'm on the safe side.

But for now I'm happy for a 100% stable FX-60 look-a-like

benktlottie ....what cooling is that on m8 ??

benktlottie ....what cooling is that on m8 ??

Air cooling, Arctic freezer Pro 64. Cost me 14 quid from OCUK a couple of weeks ago. I am very impressed with it, considering I bought one of those Vapochill Micro Extremes the day they came out for £35. Doesnt even come close to the 64 pro in terms of temps and noise.

Update on this 170. Can't get it stable at 2.9ghz on any voltage. Managed to hit 3ghz in Windows using Clockgen, but crashed before I could paste the screenshot. I'm just wondering if my PSU is leeting me down. I have a Hiper 580w. I suspect the Hiper is solid though, and maybe with water this is a 3ghz chip. But done the water and Mach 2gt before, dont wanna get back into it to be honest. She's completely stabe on 2.85ghz @ 1.425v so Dual fx57 plus speeds for half the price. Nice. (This 170 is basically an FX60 anyway with the same stepping)

Also, I'm using 2 x 1gb sticks of RAM. I wonder if she'd be more stable with just 1gb ? what dyou guys think ?

Another update.

I'm at 2.8ghz, after finally finding the divider for the mobo, sill me , and i'm happily at 2.8ghz and all seems to be going well.

I'll be aiming for 2.9 possible 3ghz tomorrow.

Just did a 32M super Pi at 2.85 ghz (285*10) and got the following result. Temps didn't go above 47C.

Stock volt goodness



Another 408L

hmmff, I got a 434 when they were supposed to be good and It wont do over 2.6 on stock, and I recieved a 408 yesterday from here and that is the same.
I must be doing something wrong or i am very unlucky. They were both very low batch Numbers maybe that has something to do with it.

I seem to have the same setup as you Hesky, what ram divider/settings are you using and what voltages for the chipset/LDT ?

 

[Hesky82]

ok, if you want try these dram settings out......

Max Async Latency - 08.0 Nano Seconds

DRAM Drive Strength - 5 (weak 3)

And try these 3 relaxed tref settings out and see which works best for you, 1168 work best for me...

0908= 100mhz(7.8us)
1032= 133mhz(7.8us)
1168= 166mhz(7.8us)

These few dram settings are key to gettin a very fast clock at very low vcore, worked with my 146 and seems to work just as good with my 170. these are specific to my dfi board bare in mind, not ram not cpu just mb. this is what I have experienced.

I always run 1.3v ldt and 1.6v chipset. Actually fine at stock but a little extra voltage will only help, providing mb temps are safe.

cheers

With that setup you should easily get 2.75 with a 408 in my opinion as thats what mine started at as well as a few others - aadmitedly i dont know what yur mobo is like clocking wise but its meant to be reasonable

 

[Devious]

Thanks Hesky, ill try them later. I do actually have Ultra D mobo too, i just need to update my sig. Did you have to do any burning in to achieve 2.8 at stock and is that prime stable?

cheers

 

[Hesky82]

yeah I remember you saying you had an sli mod ultra-d so I ignored your sig
I've never bothered burning in any cpu I've owned, tbh I think its a complete myth. more beneficial to spend the time tweaking your dram settings I believe.
yes dual prime stable, and more importantly to me game stable.

 

[Devious]

Well ive tried everything and cant get it it above 2.7, I dont even know if thats 12 hour stable tbh. Pretty miffed paying over the odds for another average clocker but didnt mind as everyone else's seems ace, but thats the gamble, trust me the get the bad egg again

Wonder if I can rma it

 

[Hesky82]

do you want to try my exact dram settings I use for my hz's

here they are anyway....

Command Per Clock (CPC) - Enable
CAS Latency Control (Tcl) - 3
RAS# to CAS# delay (Trcd) - 4 Bus Clocks
Min RAS# active time (Tras) - 8 Bus Clocks
Row precharge time (Trp) - 3 Bus Clocks (or 4 if error)
Row Cycle time (Trc) - 13 Bus Clocks
Row refresh cyc time (Trfc) - 16 Bus Clocks
Row to Row delay (Trrd) - 4 Bus Clocks
Write recovery time (Twr) - 3 Bus Clocks
Write to Read delay (Twtr) - 2 Bus Clocks
Read to Write delay (Trwt) - 4 Bus Clocks
Refresh Period (Tref) - 1168 (500 - 1500-ish)
( Write CAS Latency (Twcl) - Auto,1 )
DRAM Bank Interleave - Enabled

DQS Skew Control - Off
DQS Skew Value - 0
DRAM Drive Strength - 5 (weak 3)
DRAM Data Drive Strength - Auto
Max Async Latency - 08.0 Nano Seconds
DRAM Response Time - Normal
Read Preamble Time - 05.5 Nano Seconds
IdleCycle Limit - 256 Cycles
Dynamic Counter - Enable
R/W Queue Bypass - 16 x
Bypass Max - 07 x
32 Byte Granularity - Disable(4 Bursts)

these settings see me to 2.9ghz with my ram running at 265ish mhz on the 180 divider and a tad more vcore, give them a try.

 

[Hesky82]

you can easily tighten them up once you get your overclock stable, thats what I'm doing now

I have basically the exact same setup as you regarding mainboard, ram and cpu, the only thing that struck me was that yours is o551 where as mine is 0550

Also you shouldnt need that much voltage - I am currently on 1.425v ( which CPU-Z sees as 1.392) and even thats high compared to some

I feel for you if you really dont have any further luck ( I am hoping with my zalman fitted at the weekend I will get a small boost from that also- as i am on stock cooler at the mo

 

[Hesky82]

the stock amd heat pipe cooler is pretty good to be fair

Hi guys,

looking good so far but can I suggest you all slow down a bit and get some *meaty* stability tests done

32MB Super-PI is all well and good but I seen plenty of systems crash out during use even after that.

How about Sp2004.exe (small ffts) and Prime95 *max heat* options on both cores at once, while its doing that run 32mb Super-PI. After Super-PI has finished load up 3DMark03 or similar 3D-Demo and leave it looping for 1-4 hours (with all four primes still running in the background/2x95/2xSp2004).

My 170's are both 0550's its my 165 in my sig is a 0551 and needs volts.

Hmm, i'm in the middle of doing a prime atm, might have to do the others. Seems like a bit of a challenge...
