For now I am satisfied though!
O btw, this board is awesome~ So much information available from the community here... It's great:woot:
I did this approach..it is a pure waste..I have a 165@2610 1.49v , got 170 hoping to 0530 from monarch ended up with a 0546 xpmwQuote:

gotta start again
My point as I digressed is the difference between 2600 vs 2700 is zero....you will chase your tail for nothing
I wish I never bought my 170..I have to sell 165 now:stick:
I have my 170 0546xpmw going at 2880 @1.6v now that she's nekkid:D
I have the same stepping, and I'm stuck at the same speed. I went ahead and ordered a new one. I really wanted at least 2.7 so I could run 300mhz with my memory(tccd). It should be in tomorrow:banana: I'm going to put the lesser oc on fleabay. I also have the thermaltake cl-po114 on the way:woot:Quote:

How much and where can I get one? :)
Also, do you guys think its too much volts if I put 1.57v?
Its putting me stable at 2800 and maybe more.
opt 170 0546 xpmw w/ si-120
IHS still on
What are your temps? It seems a rule of thumb is to try not to let them go over 50C. Afew degrees over under full load is fine, but not all the time.Quote:

I would weigh the results of the increase of speed with the increase of voltage. For instance my opty 170 works like so:Quote:

2.7 at ?
If my otpy was stable with 1.555 volts, but I had to give it .1 more voltage then it wouldn't be worth it to me. However, if I could get to above 2.8 with 1.55 then I would turn up the voltage:cool:
mine is like this. i didnt test any in between.Quote:

I have a CCBWE 0534 SPMW and it needs 1.6 v to get into windows at 2.6ghz
Then after 1min 30 core 0 fails
Is this a really bad stepping or something?

My opty goes:
2700 / 1.4v
2800 / 1.48v
2892 / 1.6v
All tested dual prime stable.

Drop your memory timings and the ldt bus to 3x and then see what you getQuote:

man this opty is bad I hope its not my mobo
running a zalman 9500 heat sink and the temps at 1.6 are ok at 51-54 load but it doesnt stay in prime long enough 1 min 30 sec:(
I have to have 2.6ghz at least!
Going on a whim here, but try a different divider. I noticed on my first one that my machine would not boot up at certain dividers, mainly the e6 revision dividers. If not, ebay is your freind. There's a fool born everyday. GL
Currently working on Rev. 2 of the RAM cooler... Things are looking better this time now that I have a professional quality aluminum ruled t-square and a 1.5" hole saw. The hole saw is bein a bit shiesty though, it really bites that plexi and im afraid it might crack it. Trying to be super careful this time though. If it doesn't work after this, I might give it one more shot, after that I give up, lol.
since you are looking at improving it i guess you can look at bigger fans.......92mm single fans would probably be better for quiet operation and decent airflowQuote:

ON THE TEST BED:
CBBWE 0545 XPMW OPTERON 170
DFI ultra-d NF4 SLI modded rev "AB0"
Enermax Liberty 500 watt system power supply
2*512 PC4000 mushkin redline UTT rams
Boxed AMD cooler with 25f outside and window open
IHS on /w arctic silver ceramique paste
2.7 @ 1.45v
2.8 @ 1.55v
2.85 @ 1.6v
going for 2.9 @ 1.65v
Those are far too large to try and mount to plexi... 40's or 50's are going to be the best sizes to easily mount. I've got two of the fan holes cut and drilled, it's just inevitable to keep it from cracking in the thin area but i dont think the cracks I have this time will be visible nor cause any problems as it's just between the mounting screw and the fan hole itself.Quote:
