Nice OC Donut :) have you tried tightening your ram timings?
Click to expand...

Yea. I orginally had 2.5-3-3-8, but it wasn't prime stable. :( That's value ram for ya I guess.
 
After a wile of use my chip seems to be clocking better now. I had allready stabilized 2.8Ghz, but the votlage was a tad too high. (fans had to be on 12v) So I have started over with stock voltage. and been moveing from there for the last week.. I stoped prime with only 4 hours because im gonna game now :)

2.7Ghz, 1.4v Air cooled by XP90, 92x32mm fan on 5v

biovader and YourPaceOrMine... i need your final stable speeds :D
Click to expand...

2.8ghz was my final speed :D but it was at 1.65 volts that i got it completely stable.. not 1.54. sorry, havent been on here in a while... studying like a madman... i dont even use my computer anymore... i just use my laptop =(
 
Got my 3700+ Winchester up to 2640 MHz which is 11x 240 MHz. I cant take HTT above 245 without BSD and memtest errors. I have not tried memory dividers, the ram (gskill, 2x512) is running 2.5-3-3-6, kind of loose. Heat sink is a XP120 running 50c at full load.

Is there anything I can do to get my speed to 2.8 like the rest of you guys?

I fried my BIOS, as soon as I get another one from EVGA I will post validation and screens.

Could anyone help me with overclocking my computer or tell me where i can get the imfo specific to my computer please?

I understand the concept but when overclocking , i get a black screen.
I am told you can clock this processor easily to 2.8Ghz. Yes please!!!!
 
Ok well I have gotten the max overclock on my new Opty 165 now.

OSA165DAA6CD
CCBWE 0546SPMW

The Max Overclock I could get was 2700 (300x9) with 1.536V on stock cooling. Although after it finished priming for about 4 hours I stopped it cause it was cooking at almost 60C :eek:

I can also get

1.456V : 2600
Stock Voltage : 2475
1.136V : 2150
1.04V : 1800

I like the low voltage stuff, I am currently running it at 1.136V and 2000 (8x250) and the load temps barely break 40C.
 
Hey guys,

I need a little help (the supergod eclipse maybe?)

I've read a lot about the memory divider. However, the BIOS that came a couple days ago with my a8n-sli premium doesn't have a "memory divider/ram divider/any other name you could call it" option. I'm on a page with most memory options in timings. There is only one field measured in MHz, and that's "Memory frequency".

Memory speed and the divider are different right? I figured the field listed above must be speed because it cannot be set lower than 200 MHz.

So, does anyone know where that field is in my BIOS. Advice would be greatly appreciated.

Also, I tried to figure out my 3800 X2's top speed by setting everything Eclipse recommended, with the exception of the memory divider, and also 1.472 on the VCore.

Anyways, after crashing at 253.54 HTT and x10 multiplier, I tried 252.78 HTT and x10 multiplier for 30 minutes on prime95, with no errors. However, occasionally my screen would black out for a split second and then come back, even though prime95 reported no errors/warnings. Note that the monitor is an old dell CRT. Should I be concerned with that?

Thanks in advance, and when I get these problems worked out I'll post my full overclocking performance.

Regards,
sedgie

3700+ KAB2E 0532XPMW Batch # 0882
TT Big Typhoon,going under water this week.
Click to expand...

Nice chip... I have the same one, not sure which batch, but it's an KAB2E 0532XPMW... pretty much an unmarked FX57! hah.. not really, but hell, it runs at 2.8ghz and 2.9 even with stock vcore! crazy. if my memory would run a little faster I would run the cpu at 2.9... lol. When I use a divider it I get random reboots during long gaming sessions... I might crank the VDIMM up to 2.9 and try 265 @ 1:1 again this weekend and see what happens... this chip will run at 3ghz with 1.5 vcore but I have not been able to stablize it... it kept getting really hot when I ran prime, so I am thinking about popping the ihs off soon... let me know how your watercooling goes. :)

it's the same thing :D

the reason you only have 200mhz is because asus is silly and is actually giving you the ddr speeds:
200mhz = 100mhz actual ratio (1:2)
266mhz = 133mhz (2:3)
333mhz = 166mhz (5:6)
400mhz = 200mhz (1:1)
 
Manchester 0534? I think thats the week, its one of the first Manchsters out, x2 3800+. Does 2.4ish stock volts, currently running at 2.6 1.4vcore. Thing does not respond to high volts, either that or this Mobo is crapping out about 270 HTT, cause even 1.55 is not stable at 2.7 GHz. Certainly more than fast enough for me though.


Also have a winchester 3000 CBBID 0503. Supposed to be one of the worst ones, but does 2.6 at 1.63 vcore.
 
I'm not an extreme overclocker....just someone that wants to unlock the potential of my system without taking risk of overheating or premature CPU death. I've heard that my system will do 2400 (instead of the default 2000) without too much problems, using the stock heat sink and fan. Is there an easy way to just set this up without testing things to the extreme?

If someone can give me a very brief "how to" on adjusting my settings, I would be eternally greateful!

***Nevermind! I'll just let the MB do a 10 percent overclock for me...that will get me by until I get an X2 CPU.
 
I was just looking @ my CPU, and the last two digits (or FF in the guide) are BW, which don't appear there. Do I have some unrealeased CPU? It's a 3500+ venice core
 
Well, I have been running my Opteron 148 CABYE 0540 FPMW 24/7 for two weeks at 3.0 GHz with 1.56 V on water. Idle temps are around 38C and loads to about 50C. It is SuperPi stable and OCCT Torture passed. Pretty happy with the results. Now, I have a 170 on the way for some dual core testing.

CPUz verification

I also have a CABYE 540 146 that does the same. It's in the second PC. Would have kept that, but I needed the 148 multiplier since the 2 GB DDR does not clock as well as the 1 GB kit (310 FSB 1:1. 1T). Had a 146 CAB2E 0536 that peaked out around 2.7 GHz. Used that for another build and left it at 2.5 GHz.
 
Hi everyone. First off I would just like to say a big thanks to Eclipse, this is a spectacular guide you have here. I have had some trouble however, and was wondering if one of you could help me out. I am overclocking my AMD 64 X2 4200+ and A8N5X motherboard.

I first must say that I am not using clockgen, since it does not support my motherboard, and am instead using Asus's own overclocker. It gives all the options I need to do from XP, and works just fine.

I am following the very first step of this guide. When I increase the FSB everything goes fine, until I reach about 227-230 Mhz. At some point around those numbers, my computer crashes and this screen comes up:

I then must go into my BIOS and turn my FSB back down to normal in order to boot to windows.

Can anyone help me out?
Thanks in advance!!
 
You have to loosen up the memory timings as you increase FSB. That is probably what you are seeing. What timings are you running?
 
I believe I am running defualt right now, which is 3-3-3-8 on two identical 1024 MB sticks.
 
Are those the default timings rated at 3200. Or, is is DDR 4400 or the like? Or, better yet, what RAM are you using? (ie. OCZ Plat 3200 2-3-2-5 2 x 1024 MB)

Not great I know, but I needed 2 GB and my funds were limited. It is Corsair though, so I am assuming that of the "value" ram that this stuff is fairly good.

Make sure you use 2.7 V. Then, loosen the memory to 3-4-4-9 and see if you get a little more FSB. You might be limited. A good set has 2-3-2-5 at stock and can loosen up quite a bit more.

Setting an affinity doesn't really help with BF2.....So will fix #2 be safe with WinXP 64 bit's Registry? I assume so, but I don't feel like having myself do windows recover if I screw up. :)

Kids, don't try this at home!

You think 1.70V is a lot? I went as high as 1.74V (1.55V * 112.0%) but the extra voltage didn't make my system stable at my next frequency goal of 2,805MHz. Dual Prime95 SmallFFT ran for like 2-hours but then failed. I dropped it to 1.70V (1.55V * 109.6%) to check the CPU out to get the maximum speed out of it and run stability tests on it and also to use the system to play games. If you care to see the stress testing progess that I did with my system just check out the posts in this thread XtremeSystems - The Official Dual Core Opteron Overclocking Thread.

But you are right about the voltage being very high... too high even for my tastes. I kept pushing the voltage on my processor up and rolling the dice with every single uptick of the settings. I was playing Russian Roulette but it seemed that I kept on getting lucky and hitting those empty chambers every time. I sweated with every reboot, hoping for stability, praying for a quick crash if something is wrong, or dreading a fried processor and the black screen of nothingness. Fortunatelly my luck lasted long enough for me to find the frequency maximum of my processor at ~2,750MHz. Phewwwwww.... :D

Right now I just started the voltage optimizing routine of stress tests to try and determine how low can I go and still maintain 2,750 MHz stability. I'm testing 1.55V (1.55V * 100.0%) right now and I'll see if that'll hold. Most likely it won't since I had to do more than than on previous tries to even hold 2,700 MHz. Once I find the minimum I'll post up the results. My guess is that it will be 1.625V (1.55V * 104.8%).
 
techhead has a good point guys. remember that i created another thread for discussion. it's difficult for me to go through and update the DB when i have to sift through all the posts of you guys discussing your oc's to pick out actual results.
