Looks like Eclipse isn't updating this anymore

my apolgies! :( :p

as for the ht link.. in your board, 800mhz = 4x, 600mhz = 3x, 400mhz = 2x, etc etc :D
 
This may be the wrong forum, but why am i not being successful in overclocking? I have a MSI K8N (7125) motherboard. Why is it when i try and set a couple settings in the BIOS i can't seem to get it to save multiple changes. Also when i try and overclock past a certain point, when the BIOS trys to save the the new settings, there is no (saving) beep and it doesn't even post. But in Windows when i set everything to stock, and then i change the clock using clockgen, i can get much higher than i could ever save in BIOS. Please help, this is the second motherboard that this problem has happened on.
 
This will probably be my 24/7 OC. I have had some problems so far max OCing this chip, but as you can see it has alot of potential. As you can see on the bottom right, idling at 32C now with Hyper 6, woot!

FSB (HTT) OVERCLOCKING (first step!)
Armed with those programs, reboot into the BIOS and make the following changes:
HT link multi = 2x (edit: some boards have weird quirks, try 2.5x or 3x instead if you feel this is an issue)
CPU multi = 5x
RAM divider = "100mhz 1:2"


Boot back into windows after saving those BIOS settings and do this:
open prime95, and start an "in-place fft" torture test.
increase the FSB (HTT) with clockgen 2-3mhz every 15-30 seconds.
keep track of the speed of the FSB (HTT) as it's likely the computer will reboot before prime95 throws an error. whichever one happens though, remember 5mhz under the last speed you set.

write down this number somewhere, as it is the MAX FSB (HTT) YOUR BOARD CAN DO without tweaking other things. if you can't break 250mhz, something is wrong. we'll go over troubleshooting later.. or in person. haha

Could you elaborate on this a little bit. What voltages can you increase to get a higher HTT???

Is eclipse still updating the table?

If he is, here is my info (these are just pre-liminary results)

ADA3700DAA5BN
CABGE 0522 XPBW

260x10 (2600) @ 1.36 volts on air (xp90)

Prime


SuperPi


OCCT


CPU-Z and Smart Guardian



UPDATE
I am now at 2700MHz by way of 270x10 on 1.4vcore and 2.7mem.
I will post pictures later today

CBBLE 0512DOBW


24/7 overclock settings are in my sig
Screenie shows 32m supahpi and my 24/7 settings. If you REALLY want some prime screenies i'll run em.



She's got a bit more overclock left in her yet. 2800 is rock solid however.

Updated original post.
 
baron and aaron, since when was simple superPI 32m stability good enough. don't make me tell you to read the rules ;) :D
 
Got a new sandie 3700 today... it's a newer stepping, KAB2E 0532 XPMW same rev E4 as most -
kab2e.JPG

It's not as voltage thirsty as some... right now running @ 2805 with only 1.49v (255x11 mems 1:1 fsb 2.5-3-3-7 1t)... 1M super pi 30 secs and primed for 4 hours, played some games, seems solid. I will prime over night for more confidence in these settings. I had to dump my htt multi to 3x and now that's running @ 765... I was wondering if maybe I could get away with running that @ 1020... or would it even matter for overall perf?

EDIT: I saw a rev E6 sandie 3700 at XS and it's default vcore was 1.3v! they had that running @ 3.0ghz @ 1.53v. lol. crazy! keep an eye peeled for these baddies. :)

Get killed. Er, I mean, fine I'll prime it overnight. Good lord.

DFI Lanparty UT SLI-DR
 
my cpu primed for 10 hours with no issues at 2805 with 1.49v... yeah! load temps now @ 39c. Hey - this is a really lame question, but will Smart Guardian only work with a DFI mobo?

Instead of using the regular SuperPi, you should download SuperPi Mod (v1.4).
And yes Smart Guardian is made by ITE to support DFI only AFAIK.
 
ok - I will download that one! Thank you both for the SG info also.

ok - whew... just under 30!

That's pretty good. I tried 2.8Ghz today on stock voltage and it was a no go, so I'll have to bump voltage a little to get there. I will be trying later tonight or tomorrow.
 
That's retarded, I'm at 2850Mhz and my SuperPI time is 30.354.....

I want my extra second!!!! :( ;)
 
ok, I just did 2.5 hours of Bf2 @ 2.79Ghz on my Newcastle....life is good, I think I can make do with this... ....


errrr... me wants 1mb cache...
 
ya - the KABGE and CABGE stepping ones seem more voltage hungry than the newer ones.. I have a feeling I will be able to do 2860 (260x11) with my current voltage settings... We'll see. :)

Well, I primed over night and just checked on it, and it failed.
Damnit...The weird thing is it passed OCCT and SP2004, and tons of other benching software along with some gaming.
All in all, I'm not sure if more voltage (more heat) will justify the 100MHz gain.
I'm extremely happy with 2.7 at stock vcore.
 
Here's prime, i'll edit this post and include memtest ( I guess I take a digi shot of the screen?) when i finish that.

 
I had to raise my vcore to 1.518v to stablize some crashing I was getting on games... but it's solid now @ 2805. I get 29.75s 1M super pi times now. weeee! adding the voltage acutally really improved those times a little. My games sure like this cpu. wow. It made a noticeable difference... I was able to add another level of AA or a couple levels of AF (or both in some cases) to most games while keeping the performance levels I have before with the winchester. :) Even the games which seemed gpu bound, but then again, I could very well have been (dare I say it) cpu limited or "bottle necked" with my SLI setup and that old processor... this new setup seems to compliment the video sub-system well.
 
Roliath said:
Wow, thats a high vcore!
I'm testing 2.8GHz right now, with 1.47 vcore, and 2.8vdimm (280x10).
Click to expand...

Actually, that was incorrect on my part.

The actual voltage that I'm running now to stabilize games from crashing is 1.475*113% = 1.66vcore.

You might think this is high but I idle at 34-36ºC and load at about 46ºC with my XP-120 that has a 105CFM YS-Tech on full power...

I'm am real happy at 2.85Ghz! It's a pretty extreme speed that not many A64 users reach, I'm about 100Mhz above average lol ;)
 
Nice... I am going to go for 260x11 tonight... I'll have to change my memory timings, so I am going to bench before and after results. :)
 
What even more cool is that I have my RAM timings at 6-2-2-2.0-7. What should my tRAS be/ should I try for 5?

It's not like the nF2 boards where they ran best at 11.
 
That would be the lowest value which could be stable.. 2-2-2-5 is super high performance settings... what speed are your mems @ again?

I am looking @ 3-4-3-8 for 270mhz... overall, it will be a decent improvment, even though I add some latency, it won't matter at those speeds... :)
