1700+ Tbred B doesnt overclock so well.

[Sniper82]

Well it seems to do 1.83Ghz at default voltage(166FSB) but when I try to up the voltage to 1.75v and the FSB to 180 its craps out on Prime95 after about 20mins. Its a JIUHB Tbred B. Maybe this Tbred just doesnt want to o/c as much as others?

I am running a 8RDA+ with latest BIOS,OCZ PC3200,Volcano 7+(temps at 40-44 celcius),AGP locked at 66,ect. I was thinking I may have a setting wrong or something in the BIOS but I don't know much about Nforce 2 since I'm a newbie to anything other than VIA.

Any ideas?

 

[pillage2001]

Why not oc using the multiplier first before using the FSB??? Given that the Epox board is a great overclocker but there are always duds around. Try overclocking through the Multiplier before you do it through the bus.

 

[Sniper82]

well it failed Prime95 at 12x166FSB@1.75v

 

[pillage2001]

What's the full markings on the chip??? What week is it made?

Tried 1.8v??

 

[Sniper82]

havent tried any higher on voltage. Don't know the exact markings and don't want to pull it out unless its really important. What would be the highest one would want to run one of these air cooled?

Highest what?? Highest OC or voltage??

Anything below 1.85v is safe I guess. As long as the temps are fine, you'll do good. Up the voltage and see if you can get it to not crash in Prime.

 

[Sniper82]

voltage . So 1.85v is fine as long as temps are in the safe zone(40-55 celcius)?

My CPU has gone up as high as 68 C.

It's still running strong till this day.

Just try to keep it below 60C. You'll do good. I would suggest getting another Xp1700 though seeing that it's rather cheap these days.

 

[Sniper82]

whats bad is I just got this one today

Anyway what torture test should I be using on prime95? Is there maybe another one just as good? Hows 3Dmark2002SE? I know its just a bench but I heard it stesses the system alot.

BTW what settings do you use to run your Tbred(FSB/multiplier/voltage/ect)

 

[pillage2001]

Other members will suggest 3dmark 2k1SE as it stresses the overall system more than 3dmark 2k3. Loop it together with prime and see if it crashes yoru system. I basically just run prime95 to see if my system is stable dude. That's the one I trust most, sadly.

I'm at erm......146x16. Using 1.7V as of now. But mine is a special Tbred.

 

[Sniper82]

Well I will have to look into it more tomorrow. Got a couple more questions. How long would you suggest run Prim95? I mean how long would you say it would need to run without failing before you could say the CPU is stable at a certain speed? Also when I find the stable spot would I be better off running low multiplier/high FSB or low FSB/high multiplier? Right now I'm running 200FSB/9.5 1.75v and Prime95 is running fine but its only been 20-30 mins.

I take it your running a low FSB because your mobo?

Thanks for all the info BTW

 

[BDSM]

Have you tried prime at default clock?. or close to default clock with 166 mhz fsb?..

It could be other components at fault, not just your cpu.

Low FSB because I have a KT266A board. I don't know. Any time between 6 hours to 24 hours is good. Personal preference though. I never ran it more than 2 hours but I've not had problems with my oc thus far.

Low multiplier, High FSB.

 

[jiffylube1024]

Sounds like a "dud". I have one of those also, it tops out at ~2 Ghz.

My 1700+ (JIUHB DLT3C) is running happily at 12x200@1.75V - it's a really nice chip. Can't get much more out of it aircooled (SLK800 + Papst 40cfm), 12.5x200 isn't stable no matter what voltage I give it.

Just ordered a couple of Barton 2500+ AQZFA to play with and see how they clock, also got a Thermaltake Aquarius II on its way for a quick first play at watercooling - that's why I went for a cheap and cheerful kit rather than 'pro' equipment before the comments start flying in.

my 1700+ JIUHB DLT3C is running at 12.5x200 @ 1.75V = 2300MHZ using SLK-947U + Vantec Tornado 92mm @2600rpm

 

[Sniper82]

what torture test do you all use on Prim95? I just gave $35 shipped for it and the dude threw in a older Matrox video card that I needed for free so I got a good deal on it. If I can hit right at 2ghz I am happy. Beats the Pally I had.

12.5x200=2500, in which case I'm jealous :disgust: 11.5x200=2300 in which case I'm happy

 

[Sniper82]

I don't get it. Every app I go into shows it running at 1.5v(default).

Sandra,CPUID,ect

BIOS is showing 1.75 though. Could the voltage not be set up right? I have the latest BIOS think a older one might help?

sorry I mean 11.5x200 = 2300MHZ

I'm confused. Are you on a Pally or tbred now???

 

[Sniper82]

Yeah currently using the Tbred B. Might as well be the Pally. Heck I bought this Tbred B thinking most/about all overclock 2ghz+ no problem. Man was I ever wrong. The Pally did 1600+@2100+ 166FSB default voltage.

This is truly sad. But of course its no suprise as thats how my luck is .

 

[Sniper82]

I only got a 300watt Enhance so that could be a problem. But could it really be holding me back from higher speeds?

 

[bootoo]

Use aida32 or mbm to check your voltages. And yes it can.

I know you have a tb b, you couldn't do so nicely with an A in my opinion.

I just picked up a 3rd 1700+, it's a dut3c of not a "known stepping, and I think it'll do probably about like yours or thereabouts and I'll be happy.

My 2 xpmw 0310 dlt3c's are kind of rare but they're some of the steppings that are "all that" and I got the one I'm running to 2.35 stable as a rock but my family's whining because I didn't hit 2.5. I got my 2.0 2400+ to 2.25 and thought I was the XXXt if that puts both of us into perspective; most tbred b's have serious limits. I bet you can do better but don't lose sleep over it.

Remember, those o/c results the folks post are a lot of the times barely able to boot into windows.

But from your system (I have an 8rda+ too and love it even though I can't do 220 to 230 or whatever) I think you can get your fsb up - I'd try a multi like 6, and try running it at the highest fsb/multi yu can after establishing the fsb limit for a couple of weeks and then trying again. I know burn in is a myth but it worked for me! But even so, I'd DEFINITELY check your rails, that system is starved for power somewhere I think.

I know I've learned my lesson - the psu is the heart of the system. Too bad they're like buying new tires; you can't obsess over how nice they look or how much others notice them.

 

[Sniper82]

Would say a Antec Smartpower 350watt be enough? Or should I shoot for 400watt? Kind of on a budget.
