.....and buy one of these!! Better yet, buy 2!!

http://www.svcompucycle.com/lqtamdxp17tb.html

It's just after midnight here in NJ. CPU was here when I got home from work @ 9PM. I've got this 1700+ TBred-B Core DLT3C JIUHB 0319 running 2.3 GHz (11*210 FSB / 1.7v ) and it is aircraft carrier stable!

That's an 830 Mhz OC and I haven't EVEN begun to tweak it out or test different chipset, memory or CPU voltages. Who knows where the ceiling is on this thing. I laid the wood to it on a 12x200 boot and it booted into windows fine but I think I had too much voltage on it ( 1.85v . default is 1.5v ) and I got some explorer errors after running some benchmarks w/ Sandra '03, so I got out of there and laid off the juice a little.

This thing is standing toe to toe w/ my Barton 2500+ which will ahem, "only" hit 12x188 (2.27 GHz ). Barton will have nothing to do with FSBs over 188 and be stable. Only the 512K L2 cache is keeping the Barton in the hunt. Barton is nicknamed "Gary" after Sponge Bob's pet snail.

In fairness tho. I'm using a CAK II 38 / Senfu 7300 rpm on the 1700+ right now. The Barton was using an SLK800 w/ a 52cfm 80mm Mechatronics fan. Have to try them with the same fan / HS for it to be a fair comparo.

Here's some benchies (props to Nascar for the hosting.

The HUH? Please tell me I have been doing it wrong so maybe I can get my A core TBred a little higher. I thought when over clocking and you had errors or crashes you upped the voltage not lower it. I have mine at 10x180 with vcore at 1.80 (default 1.50) right now and it just wont go any higher no mater what I have tried. Are you telling me I should lower the vcore?

tbred a's aren't notorious for high overclocks... the b's are the ones that u can really crank up and thats what vid has...

damn double post...

On several occaisions I've found that lowering voltages can be just as effective as raising them. Provided they've already been raised in the first place.

Yeah I realize that but have just never heard of lowering the voltage to fix errors when over clocking. Might have to give that a try.

Vid how low did you lower your vcore ?

Seth · Post by **Seth** » Fri Jul 11, 2003 12:36 am

WOW. Thats faster than my pos Xp2000 @ 1.67

I think i should buy one of those... But

Would it be able to work with the mobo i have now?

And would the mobo i have now be able to let me OC it well?

My mobo is

Biostar M7VIG.

i dont think i want to spend allot on a new mobo.. as i will be spending my 6++ on that Chip.

it wil lwork with your board probably. but it all depends on how well your board OC's to see if its worth it.

Since your using regular SDRAM probably not.

Vid: Nice overclock! Might look into that to fully use my PC3200 Corsair XMS memory.

Woot - nice find!

Best part is that svc not only guarantees the stepping but also the 0319 ( code for week 19, 2003 ). On the other hand if you order from newegg, you're liable to get anything. I read on one of the bbs's where someone just got a 1700+ tbred A from newegg, having ordered it within the last week or ten days. ugh.

I bought this thing because I wasn't sure if it was my cpu, ram , chipset or PSU that was holding me back from hitting 200+ FSB speeds. At least now I know that it's the Barton. I'll prolly just drop this 1700+ in my kidz' Iwill rig and run it close to default voltage at maybe 2 GHz or whatever it will take without having to use such a loud fan. Of course they're gonna have to run folding@home in my name if they intend to properly show their appreciation.

:

To Dadx2mj,

I tend to do things backwards when I overclock. Right out of the box I'll gas the cpu to what I think it should or might do. I'll do this by putting some pretty extreme voltages to work all around. A blue screen and trashed registry in XP are not uncommon with this approach.

Then I'll start backing down speeds. Once I find a stable speed at the multi / fsb combo I like, I start peeling off the voltages in order to find the optimal overclock at the least required voltages, which in turn will generally result in lower temps.

For instance, last night I had the cpu at:

12*200 / 2.4 GHz @ 1.85v, mem @ 2.9v, chipset @ 1.7 ( explorer errors, prime95 fails )

11*210 / 2.3 GHz @ 1.7v , mem @ 2.77v, chipset @ 1.7 ( no errors, passes prime95 for an hour+)

This morning I'm running 11*200 / 2.2 GHz @ 1.65v, mem @ 2.66, chipset @ 1.6v. It's running prime95, folding, winamp, surfing etc.

The next move is to slowly walk up the FSB by say 2 MHz at a time at these settings to find the exact point the cpu is willing to run at such low voltages or figure out what might need just the slightest boost.

Hope that helps you.

Vid thanks for the advise. I messed with mine last night and have come to the conclusion that my chip just is not a great over clocker. I tried almost every vcore setting there is from the default 1.50 up to 1.90 and could not find any setting faster and stable than what I have been using (10x180 with 1.80vcore). I am ok with that for now but next upgrade is going to have to be a faster CPU.

I just got my 2x512mb TwinMOS BH-5. Damn, these things don't like the A7N8X motherboards. In the lot closest to my processor, these things wouldn't make it thru Memtest at default speeds. In the two slot further from the processor, the ram itself runs fine, but now my processor won't make it past 3 hours of P95 (I have it at the same speeds I had my Corsair at (same exact chips - BH-5) - 200x11 1.75v).

Now that you bring it up, I MAY try lowering my voltage. Sure, I don't have the same chip, but before this thing WONT boot, it'll have to be really unstable in Windows. I've spent yesterday and most of today already testing this thing out.

I just switched from the 1005 BIOS to the Uber 1004 BIOS.

What do you guys reccommend I change using the Uber Bios? I'm thinking I might bump ram to 2.9v and see what I can get and maybe bump the chipset up .1 v HOWEVER, I read that the chipset voltage options in the Uber BIOS don't even do anything. Can anyone clerify that?

I MIGHT be buying one of those.

Edit:

Vid, I thought you modded your Barton to allow you to get it over 200 FSB? (cutting the trace?)

Did that end up not working???

Edit 2:

Something else that has also occured to me is that the previous owner kept this processor at 2.4 GHz at 1.9v. So it is used to eating up all the juice it can get, he had it water cooled and it never got above 40 C. Mines been getting up to around 54 C

(1.85 full load - AX7)

Dunno about the Asus. Blade would have more info on that. As far as that Twinmos BH5 goes, I can only say that this CH5 TwinMOS passes memtest86 all the way up to 220FSB @ 8-3-3-2.5 with 2.77v on it (MBM5. At 204 FSB with same settings it passes with only 2.66v.

As far as my Barton goes, yeah I cut the bridge. It "runs" most everything at 11.5 but still won't pass prime95. I'm wondering if maybe the fan I was using on it, with the SLK800, isn't doing the job. If that's not it, then I guess I just got one that doesn't like high FSB's. I'll prolly give it a shot with a power fan next week after I see what this 1700+ max's out at.
