Neo2 Platinum & 3200+ Venice OC

[Stokes]

Duvie thanks for the tips!

The ram is in the 1 & 2 slots and I applied artic silver 5 to the chipset. I'm sitting right now at 9x300 for a 2.7ghz speed atm. And I'm about to run prime95 to see if it can go even higher. I also downed the voltage to 1.56V to see if it would work, if it works here then I probably can go even farther if I up that voltage a little more. I'm guessing the ram is what did it. But that artic silver 5 certainly didn't hurt

Finally! 280+FSB!!

I typed in my values into that ram script, and said that 166 would work out great, except I cannot get the board to boot using 166mhz and going 2.5-4-4-8 (tried 2.5-5-5-8). This is using that 9x300 for 2.7

 

[Duvie]

happy for you...I agree the NB chipset probably wasn't the culrpit but the ram slots 3-4 were really bad on mine and many others...

 

[Stokes]

Any suggestions on ram timings and setup? You seem to be very knowledgeable on this topic?

 

[Ike0069]

What are the exact full timings for you RAM supposed to be?
Find out and then try those timings. 300FSB at 166 is DDR249, so it should definitely run at the stock settings.

Also, have you tried to up the RAM voltage?

 

[Stokes]

Ram voltage is now running at the max the board allows. 2.85V (2.9V is the max safe).

Full Timings: 2.5-4-4-7

It doesnt seem to like anything at 166mhz.. what else can I do?

 

[Ike0069]

Try raising the last number to 10 or 12 maybe, or amybe even try going 3 vice 2.5. Shouldn't need to do that though.
Other than that, I have no idea.

Need Duvie 's help here I'm thinking.

very true some neo2 boards are like that....mine doesn't like 166 as much as well...

so you cant get cas 2 to work with any combination of 133 divider???

I had TCCD chipset and they seem to be fine at 2.5-3-3-8 at 296HTT with 2.8v.....


on the neo2 board 2.85v actually overvolts to 2.9v...

setting a TRCD to 2 in the bios results in the bios dropping vdimm by .1v...PPL have said get into windows with conservative settings and then use A64tweaker to set the cas timings (tweak)....

You can run a 133 divder and then get into windows and enable a 150 divider through A64tweaker...

 

[Stokes]

I left it at 133 and let the motherboard decide the timings and it put it at 2-5-5-9 with a 133mhz. Obviously thats not the best timings, but looks like cas 2 works out. If i ran a 150 divider what timings do you recommend?

 

[Ike0069]

Are you stable now at 2.7 GHz? If so that is excellent.

 

[Stokes]

I haven't rune prime95 yet, gonna do that now. I've kind of jumped the gun here and went to play BF2 while I'm using 2.7Ghz and seems ok. I'll report back in the morning on how the test did.

 

[Ike0069]

Did it make it thru the night running Prime?

 

[Stokes]

I left it for the night and it failed after one minute which was strange lol, cause I ran it for an hour before I played BF2 and ended it myself without a problem. I restarted and ran it this morning before I left for work, hopefully it's still going. Otherwise I'll back off a bit and get that 2.67Ghz or so. Not a real difference between the two, but any mhz is helpful.

 

[hmmzzz]

I thought bios 1.8 was supposed to fix the temp issues ?

edit* ah, that was not the last page,the bios thing has passed.....deleting this post would be the obvious thing to do...but there seems to be no option for that ?

 

[Ike0069]

Yea, I would think that if it plays BF2 for an hour, it has to be stable.

It does but in some ppls case it took them to flash it once or twice.....The first time I went to 1.8 bios the temps were not right...I went back to 1.41mod and flashed straight to 1.8 and the temps were fine..I just bypassed the 1.62 altogther in my case...

 

[Stokes]

My prime95 results do not make any sense.

2.7ghz failed after 2 minutes, except I was able to run BF2 for about 3 hours straight without any problems.

I went down to 2.68Ghz, it ran for 2.9 hours.

I went down to 2.65Ghz, it ran for 10 minutes

Whats up with this? This is of course with the 9x multiplier? What should I try?

 

[Stokes]

The board simply refuses to go to an HTT Ratio of 2x, which is suggested by guides when you go in the 300 range on the FSB. Any ideas why this would be do? It doesn't appear to be running stable according to Prime95 at 2.7, but BF2 says it is . Probably will have to go down to 2650mhz to be safe. Although I'm jealous of Duvie having that 3000+ clocked basically the same as my 3200+ and I paid $50 more

 

[Xcobra]

it seems like you have a dud...what are you complaining about??? you are running a cpu 650MHz over its rated speed and its stable...you got an fx-55 right there....well a 5mhz faster

 

[Stokes]

Oh I'm happy with it. I'm just trying to get everything I can out of it while I'm still in the loop and know what I'm doing you know?

2.7ghz runes stable on BF2 without any crashing, I played it for 3 hours without a problem. Prime95 won't last 2 minutes. I heard though that games are far more stress then prime95. What is the correct thing to do in this situation

 

[Cheezeit]

stokes, what stepping is your chip?

I can't say I looked

 

[Stokes]

I think I'll just go with this option:

Running 9x295

5:6 (166mhz)

Timings: 2.5-4-4-8

I'm doing memtest as I am writing this. Its looking though that I might need to back off just a little bit on the timings. Test 4 is producing errors.

 

[Duvie]

Have you tried...

1) set ram timings and vdimm all to auto...except for the 166 divider and see what the mobo sets for you....

My auto settings seem to be rock solid...the most you may have to do if it get it to produce one or two errors within 10 passes is raise the tras like a few...I like it between 8-10.....


2) turn off those memclks in the A64tweaker program....


I completed 30 passes and then turne dit off...seems solid...now I will move on...I think I am going to see what the bios thinks my best 133 timings would be at same HTT....

 

[Stokes]

Yes I did just that.

I set vdimm to auto and timings to auto while keeping 1T and 166

It would not boot, until I set the cas to 2.5

Once this was done it choose:

2.5-4-4-6

It failed memtest 4 at about 50% and then 5 too. I stopped it after that cause I knew I cant be getting those errors.

I tried 2.5-5-5-7( and 8)

and it still fails memtest. Ideas?

 

[Ike0069]

Did you ever try booting at 133, then using the tweaker to raise to 150 as Duvie suggested. This might work with some tighter timings, possibly even CAS2.

Also try going 3-4-4-6. If this still produces errors, then maybe you have a bad stick. Did you ever run Memtest with everything at default speeds (which would only be DDR400 for the RAM)?
