n00b Overclock on Barton 2600+

[KayKay]

I am trying to run my barton 2600+ (333 CPU fsb stock)

My motherboard has VIA kT600 chipset, and supports DDR400 as well as FSB400

I am trying to run my FSB at 200 Mhz, but It is not stable, Freezes during 3dMARk03

What is holding me back? Also I am concerned that my motherboard does not have an AGP/PCI Frequency LOCK, so I am thinking 200 MHz may hurt them?

Finally, I have no divider to run on my motherboard, so that doesn't help me.

thanks

The 2600 is a little tough to run at 200FSB. 2500 usually does better because the multiplier is lower.
FYI, only a few 2600s make it from 166 to 200. You might have a look at Overclockers.com & check their CPU overclocking database.

What is holding me back? Have you upped the vcore? What is the vcore currently at? Also I am concerned that my motherboard does not have an AGP/PCI Frequency LOCK, so I am thinking 200 MHz may hurt them? AFAIK, it won't be a problem at 200mhz. It's the FSB speeds in between 133>166>200.

Finally, I have no divider to run on my motherboard, so that doesn't help me. What is your ram PC3200?

thanks

As the above poster said, it may be difficult to reach 200FSB because your stuck with a high multi.

I concur.

My Barton 2600 will run 190 fsb with locked multi at stock voltage and wont budge past that.

I have a Shuttle AN35 ULTRA mobo.


I wish I would have bought a 2500.

If you have a VIA board you can mod the processor to a Mobile and lower the multiplier after you get to Windows with CPUMSR.

Without modding it you may reach 11.5*200 if you bump the Vcore a little.

 

[ty1er]

here is a silly question...but... is your barton unlocked? if so lower the multiplier.

I just did a mobile 2600 and got it to run 200FSB @ 12.5 but it took 1.7v and it wouldn't do a speck more.
Running about 100°F w/Zalman 7000

sounds intriguing. is the mod permanent? or just temporary

hmm, effortlessly got into windows at 200 MHz FSB today. Gonna Run some benchmarks, but surfing the web and listening to music seemed to be fine thus far

Try Prime95 or some games like D3 or far Cry.

I wouldnt use our database. It hasnt been updated in quite a bit.

As for the multi issue I agree wholly. This could be a bigger issue if his CPU is locked more so than a mobo that lacks BIOS options to manually set the divider for 200. Unlike the multis you can pinmod for the bus quite easily

I ran a few 3dmark03 tests, and i've been playing doom 3 and united offensive for a few hours, everything looks ok. The OC was 200x11.5 = 2300

I figured a cpu overclock would help my gaming performance, but in the two games i listed above, i still get some choppiness, at 1280x1024 HQ No AA/AF. Does the bottleneck still lie in the CPU? or is it some other issue that is causing my 'problem'

I'd say it's your gfx card, not the cpu.

but that would suck, i just bought my BFG 6600GT OC 2 weeks ago, and I am certain it can handle that resolution with ease

I have a locked barton 2600 that I upped the fsb to 200 and has been prime stable for 6 months with an a7n8x board and 2x256 kingston ch-5 ram. Running at 38,43 idle 43,50 at full load

I just built a system for someone with a barton 2500 with the Shuttle An35 Ultra and I cant get past 378 (189) fsb with 2x512 ocz performance ram!!!!! I have read other places that the Shuttle just doesnt like to go past 189 fsb.

Just my 2 cents.

Doom3 is so Vid limited that your overclock probably didn't help it a whole lot. You can see for yourself by going running the timedemo at both speeds. Doom3 benefits from Vid overclock almost exclusively and it's choking your 6600.

That's a good OC though, not much further to be had from an AthlonXP. Both 2500 desktops I've had needed a bump in vcore to run 2.2GHz so you're doing well. Best of all time though is the 2500 Mobile. 2.2 at LOWER than stock VCore and 2.4 plus with slight vcore bump. Great chip, perfect for software overcocking.

thanks. The problem is not the framerate, the framerate is great, certainly over 60, but it's just that when a door opens or something, the system really "chokes".. it stops, and then it moves on.

Here is what i hope is happening, correct me if i'm wrong. I recently took out a 512 stick of ram to put in another computer, and what is happening is the "choking" is a result of the game trying to load textures into RAM, but there is not enough free, and has to load into page file. is that all?

100*F is not hot, my old celeron ran about 93*F

IIRC, your vid card has a 128MB vram. Game specs say for "High" you need 256MB. Ultra requires 512MB.

Even with the Humus tweak, it happens with my 9800p OC'd at XT speeds too. (The humus tweak helps bring ATI cards on par with comparable nVidia cards, and was done to help with this exact prob. Texture loading at levels.) I just got used to pausing when a door opened etc.

I don't think system ram can compensate for that.

A big problem i see for some people is they like to miniaturize their page file to like 500mb or so with 1gb of ram. Newer games (especially HL2) were designed to make full use of the paging file. So I would keep the 1.5 rule in hand even with 1gb+ rambo.

I may be wrong but when I say that in Doom3 it may just be uncompressing more textures for the next scene I dont think the whole level gets uncompressed when the level starts.

I actually dont remember small glitches when i played.

BTW: has anyone here actually ever played doom3 on ultra without compressed textures (512mb vram)? Or is there no commercial card that can do that yet. i hear them 3dlabs 512meggers are poop for gaming.

Such are not yet produced. However, both ATI nad nVidia have just recently announced 512MB cards. Lord only knows when they'll actual be available. I shudder to think of the price
