HUGE leap forward with A8N SLI Deluxe overclocking

[bap4201]

actually, under normal load now, i'm getting 39c.


Thanks

Could somebody do me a favor and go through the exact steps you go through to achieve these OC's? I just want to know the proper way to keep the configuration I put together. I ask here because I am using the A8N SLI with an extremely similar setup to all of you.

Go to the Processors/Overclocking forum and look for the "Overclocking Guide" thread. It should be a sticky.

I have the same problem as you Insomniak. I just put together my SLI rig the other day and tried to OC. Everything works fine and stable, got my 3200 running at 2.5 250x10 with all the voltage settings on auto, but I keep getting boot failures when I power up the rig from a cold start. Do you guys think its the bios? Also noob question and thread hijack, but are there any crucial settings in the SLI asus bios that I need to know about?

Thanks.

Change from the auto setting to 1.6375 (seems to give 1.50 - 1.52 actual) per CPUZ and AI booster. And also experiment with lower CPU multi and settings like 234 x 12 = 2808, you can take advantage of that fine OCZ ram.
You might even get 240 x 12 = 2880mhz with ram at 240mhz, that would be wicked fast. I get an extra 500-600 points in 35mark05 running ram 232 vs 200, with the same CPU mhz.

With the FX-55 chip your overclocking range is most likely not as great as with my 3200+, but with the unlocked multiplier's the ways to overclock that chip are almost limitless. jealous I am So if you don't get the OC you want, try it a different way

288 x 10 = 2880mhz DDR333/ ram=240mhz

210 x 14 = 2940mhz ram=210

325 x 9 = 2925mhz DDR266(or AUTO) ram=217

273 x 11 = 3003mhz DDR333 ram=228 Dare we dream!!!

I'll quit now, my jealousy is increasing

Oh, and don't forget to drop that HTT multi to 4x if you use a setting higher than 220, and 3x over 260

The RAM speed makes very little difference actually. For example the difference beween 12x200 and 9x266 (cpu is 2400 in both, memory at 1:1) is less than 2% with the OCZ3200R2. See Anandtech article about memory timings. You can probaby even say that, 1mhz increase in DDR speed equals, more or less, a 1 mhz increase in CPU speed.

btw, I have my HTT at 4x with FSB of 261 mhz (261x9=2349 a3000+, 217 ram, 4x htt)

While we're on the subject of overclocking, perhaps you gents could provide some input:

I've gotten my A8N-SLI Deluxe rig up and going, and now I'm fiddling with the OC. System follows:

ASUS A8N-SLI Deluxe (1002)
Athlon 64 3000+ Winchester (DH8-D0) (2196Mhz, 244FSB, 4xHTT, 1.5125v)
1GB Mushkin Basic Green PC3200 (~400Mhz, 2.5-3-3-8, 2.7v, 5:4 divider)


Now, all this checks out in windows...The system Primed for 8 hours last night with no errors, warnings. It swallowed 4 hours of Half-Life 2 without breaking a sweat. When I checked the temp this morning before stopping Prime, it was at 44C, so I'm assuming that's the highest load temp it's going to hit.

Weird thing is, sometimes it boots perfectly, and sometimes it gives me a system boot fail. I've fiddled with the RAM voltage, and that doesn't seem to be the issue, so now I'm edging up CPU voltage. I imagine it's one of these two culprits - one of them simply needs more juice - but any other ideas?

I'm also considering taking the RAM back to 1:1 and seeing how high I can ride it, but I'll have to check the net a bit and see what this stuff is supposed to hit before I try that - get a ballpark idea.

most liekly your ram cannot go above 215, but you CPU should be able to get above 2300 at least. So I suggest you keep the "DDR333" divider and continue to increase the FSB towards 250 and beyond. You do need to increase the cpu voltage - just put it at them max of 1.65 (actual 1.58) - it causes no harm and if you want to find your max cpu speed, you have to do it with max voltage anyways

I'm quite a noobie in overclocking but I would like to try what I can do... Could someone expert recommend me some nice OC settings for this configuration...:

- AMD 64 3200+ (90nm)
- 1GB Transcend 400MHz DDR
- A8N-SLI Deluxe (BIOS 1003 Final)
- 2xGF 6600 GT's

I did overclock my old computer but it was quite simple, you could only change CPU multiplier and FSB frequency and memory timings. With this A8N board there are several new things I don't know nothing about: HT, PEG and so on...

PS: I am using AMD's boxed CPU cooler... Is it powerful enough for overclocking?!
