I think I've hit the wall with my 1700+ B

[rommelrommel]

Here's my rig:

Asus A7N8X non-deluxe
T-Bred "B" 1700+ JIUHB 0251
Albatron GeForce4 4200ti
256MB Corsair PC3200C2
Enermax 365VE Power Supply

Right now I'm running at 12.5x192=2400mHz

MBM5 indicates that I have 1.86 Vcore steady, and that's about all I'm comfortable with.

I've done both the 5V mod and the VDD mod. Both of them in concert (I didn't test seperately) led to the following results:

Before:

Maximum Stable = 2350mHz

Maximum Get into Windows and use basic apps = 2400mHz

After:

Maximum Stable = 2400mHz

Maximum Get into Windows and use basic apps = 2500mHz+ (Didn't push past there as was extremely unstable)

CPU temps under load are around 50 C +/- 2 C

Northbridge has been lapped and remounted.

Ram timings have absolutely no effect on stability, so I don't think the Corsair is the problem...

Basically, what else can I do?

Stand back and applaud. That's a hell of an overclock on just air! 🙂

i agree. my 2100+ is @ 2200 (11*200) i can go a bit higher on the fsb, but even lower fsb and higher multiplier can't get it to where you are.

8rda+ w/ no mobo mods except the JCLK jumper "mod" 😀

 

Nice job man 🙂.

THats a sweet overclock, I just wish I could push a lil more out mines, but damn 12.5x multiplyer got me set back.🙁

does the "southbridge" get hot at al?
what about the mosfets? voltage regulators? (unelss those ARE mosfets...im a bit fuzzy now lol)

Good question, Champion! I recently saw a site showing infrared images of an 8RDA at load, and it was pretty surprising how hot the Southbridge got!

Yes, they are "hot" but not unreasonably so... when I find some thermal epoxy I will throw some sinks on them but I really don't think that's the problem... they aren't much hotter than they were before.

Really, I think I need higher multipliers... I guess the chip comes out again for some L3 bridge blowing action.
