2500+ Barton won't hit 200fsb. Help? Settings?

[MeowCat]

those who can't get 200FSB out of a barton2500 is because they are on nforce2 board.

oh.. another..

At 200fsb it won't even post.

abit nforce2 v2.0 boards are good at doing that. shows how buggy they are.


Go get a KT600 and you are ready to go 200+FSB and away.

Meowcat needs to be put out in the cold!!!


There are no gaurantees that "ALL" 2500+ will do 3200+ speed (11x200) as you state...You making that statement shows your complete ignorance in this area....

I suggest you tone down the"arse", "sucks", and generally spreading of lies.....

We generally look at it this way..."Is this member contributing to the forum???" I would have to say for you that is a resounding NO!!!

ahem .. someone has not credibilty and shoots crap from their whiskers. no links to back up claims and posts utter crap.

Being relatively new to this overclocking thing, I was wondering what system instability manifests itself as (with respect to overclocking a processor beyond its limits). I recently tried to overclock my 2500+ to a 200Mhz FSB (I have a GIgabyte GA-7N400-L1, 1 GB PC3200 HyperX, and some large aftermarket ThermalTake CPU cooler) and the system posted normal, but during Win XP load, the blue screen of death came on. I set the FSB back to 166Mhz and the system works fine. I'd really like to overclock this processor, but I was wondering if I should adjust the CPU Voltage as well. Currently, its set to 1.74V with a temp of 49 deg C.
Thanks.

BSOD at load up are usually related to memory or memory timing issues...However it could be both..I have just seen more with the memory...

Try bumping up the vcore of te chipset if you have the option....Default is 1.5v but I would try 1.6v and definitely as the system is overclocked it may require vdimm of 2.7 to 2.8v regardless if you are not running the ram out of spec...

vcore cpu = 1.65-1.7v
vcore NB = 1.6v
vdimm = 2.7 or 2.8v
vagp = 1.6v

Are all relatively safe on components....Most ram of pc3200 origin is rated within that region and when running multiple sticks usually need s a boost...

 

[UptheMiddle]

After doing that, WinXP now stops at its loading of a file called Mup.sys during bootup:disgust:
The system comes back fine once everything is readjusted....this seems to be a winxp prob

 

[Duvie]

Well it sounds like the BSOD eventually corrupted the install....definitely sounded like a ram issue...

 

[JonElfson]

My 2500+ doesn't even get to 3200+ for some reason...

It even needs 1.7 volts for 2.1 GHz :\

Although it runs really cool (never goes above 40C), I feel like I wasted my money on a SLK-900U.

 

[Duvie]

I am lucky (or my buddy is!!) the one I built does 200fsb or 2.2ghz at 1.65v(prime tested for 12hours, TMPGenc testing for 8 hours)(haven't tried lower) and does 2.3ghz prime stable tested for 4 hours at 2.3ghz (209fsb) with 1.7v actual...temps never go over 50c with the 1.65v and 2.2ghz and about 52c with the 1.7v and 2.3ghz...this is with the retail HSF which by the way was the one with the copper bolted on the bottom of it.....

I will do further testing later this week but I think it has more in it...I may try to pick up some pc3500 as this pc3200 will not do as 2 even at 209fsb...

 

[Wuzup101]

Unless you got a bad board the rev 2 board should easily be able to pump out in excess of 200mhz fsb. Definitely try bumping up the chipset voltage, ram voltage, and cpu voltage a notch and see if that helps.

 

[myocardia]

Adam, you never said what your voltages were. Are you running a good power supply? Many cheap power supplies will run an Athlon at stock speeds, but as you can see, most of us overclockers have very good power supplies.

 

[chocoruacal]

Adam, when you post without listing your COMPLETE system specs, these are the kinds of responses you are going to get (unfortunately.)

Step 1 = Prime95/Memtest86 the system at stock settings for at least 12 hours each. Who knows...maybe you have a bad part right out of the box, maybe your PS can't handle the new parts, maybe you did a bad job of mounting the stock HSF, maybe your RAM and board don't play nice. OCing is only going to make it all worse.

Step 2 = Research. See what others with your board are doing. It wouldn't have taken you long to find this site. Pay close attention to the BIOS settings at the bottom Also, read thru the Abit section of Amdmb.com...much better info there than here.

Step 3 = Reality time. Not every 2500 will do 11x200 out of the box! Using the stock hsf isn't going to help that. Ignore the posts/Newegg reviews where you see people bragging about their oc...I bet that less than 10% of those folks actually use Prime95/Memtest86/whatever to test the integrity of their system. I.e. I would imagine there are far fewer stable/error free XP2500 OCs out there than we all think.

But anyway...try the settings in the link and report back (with your COMPLETE system specs!!!) And ignore Meowcat...all things equal...a 2.0 board is best for many reasons...he just appears to be ignorant of them at the moment.

 

[Blooz1]

Chocoruacal's right on this one! People here generally do lots of testing while OCing, but there are lots of other people who don't bother, but then turn around and brag all over the Web!

I've got a 2500 that runs at 2310 at 1.72V, but it won't BEGIN to pass Prime at that speed and voltage! I've had many more problems with stability testing with my Barton than I ever did with my T-Bred "B", yet the actual overclocking was ridiculously easy!

indeed. i booted into 2350 with my barton but failed prime terribly. rock solid at 2200 - 24+ hours Prime95. gonna try up it next week.

I completely agree. I've got a week 32 2500+ (that's locked) that won't do 11x200 on my board. Granted, it's an early revision 8RDA and I haven't modded the VDD voltage yet. However, I tried the 2500+ on an A7N8X-E Deluxe MB to try it on and it still couldn't go over 185 FSB.

 

[department76]

I am having a similar problem; my 2500+ doesnt wanna hit 200fsb, but does 198 rock solid and am currently running at 3000+ 396fsb. Whenever i attempt to raise the multi .5 to hit 3200+, no boot. I have the A7N8X Deluxe (only verson 1.04 :Q) and my ram is only pc2700 but its at 2.8v with lowered timings, also runs fine at 198 but not 200, though not sure if its ram or not. Ive tried at 1.7 vcore and 200fsb, but that doesnt work and 3000+ and 198fsb work fine with stock 1.65v. And according to Asus, this non-2.0 nf2 board should do fsb 400 with bios update, which i have gotten.
ideas?

 

[AdamBrouillard]

Well I got my new heatsink. I just kept cranking the voltage till I was stable. At 1.95 I seem to be stable so far at 200 fsb. Sounds pretty damn high, but my cpu temp hasn't gone above 52 celcius. Whatever. I guess that's the best I'm gonna get.

I don't really care about the temps running at 1.95v is not safe for the longevity of this cpu...you are currently running a near 20% vcore increase and rul of thumb for most is not to go over 10%....p4's 1.525v default don't go oevr 1.7v max.....Bartons don't go over 1.8v max...

Face it...It just wasn't the best ocing chip...sell it and try another if you have to have it....1.95v you may be out of a chip altogether in a few months....

Hi department76

I have a similiar board and can't seem to get much about 180 FSB - from what I have been told it is down to my mobo and lack of a PCI / AGP Lock :- Quote :-

"TLMiller is right...KT400 do usuallly get any higher 180fsb. Reason being is that KT4 mobos do not have a PCI/AGP lock...instead they utilize dividers. all KT4 mobos have a 1/5, no 1/6. With the 1/5 divider, the KT4 would be running your PCI bus at 40MHz if you set the FSB to 200.. (200 / 5 = 40Mhz )..Most hard drives don't withstand more than 38Mhz."

My question, does you mobo have this PC / AGP Lock? or have you managed to get around this?

Thanks

Mark

 

[MLJGTI]

Forgot to add Specs

Mobo - ASUS A7V8X
AMD XP 2500+ @ 1.98 (FSB 180 x 11)
MB Temp 30/32 Idling
CPU Temp 45/47 Idling - Up to 55 Load - (CPU Fan 2600 Speed)
Vcore 1.65 (Actual 1.69)
Corsair 512MB - PC2700 DDR SDRAM 184 Dimm
Geforce Ti4200 64MB
Coolmaster Aero HSF (Adjustable from 1600-3800)

 

[department76]

yes, the a7n8x dlx has the lock, I think that has something to do with the nforce2 nb.
edit: while running at 3000+ speed with 396fsb, idle temps are 38 C and load is ~46 C with volcano 11 at 1/2 speed. I dont think cooling is a problem.

You are such a Tard man. go away and come back when your 16.

Once again, NesuD, I got to agree completly! But if he's to return when he's 16 that'll take him another 13 years I guess. Hope I won't be around then anymore ... too old then for this kind of crap!

 

[smokedturkey]

after all, the barton is only 166mhz spec. 200mhz is quite a bit of a stretch. FSB and Memory bus two diff. animals

Well, you're obviously a newbie! My Xp2400 T-bred B does 205, Prime 95 stable, and it's "supposed" to run on a 133 fsb. Hey, I'm considering changing motherboards, because I think my Epox is what's keeping me from a higher fsb...

edit: I forgot, welcome to anandtech.
