Help me overclock my P4 3.0Ghz

AlphA · Post by **AlphA** » 26 Oct 2005, 20:26

Cool - Actually, just ran SuperPI again ... I'm down to 37 seconds! Ran the test with Norton disabled and the MSI hardware monitoring application closed.

Just FYI, I managed to get my RAMmmup to 420 earlier, but was running it @ 420 from 400. Is there any difference between the two?

Below are my CPU-Z screen shots of the config...

Thanks again for all the advice

do u mean the difference from 400 to 420 as opposed to 333 to 400. C my post above i asked a couple of Q's about ur mobo.

No, my mobo does'nt have 1066fsb support...Its an MSI running an Intel 915G chipset. When I dropped my RAM to DDR333, the CL changed to 2.5.

Ok, initialy, I ran the CPU at DDR400 (stock)....now, since I pumped the FSB to 240.....I dropped the RAM too DDR333 so its no running at 401Mhz with the 240 FSB. Get it?

What I'm trying to say is that it was running ok at 420 (from 400). Would it be okay to still bump the RAM up to 420 (from 433). Is that more risky?

so that wud put u at 1000 fsb. The ram might handle it, try 410 first tho.
Im more concered about the chipset, put a fan on ur northbridge.

but as i sed, the worst that can happen is that ur pc wont post and u will need to reset the bios.

AlphA · Post by **AlphA** » 26 Oct 2005, 22:35

Look, I dont think I should push it anymore....I'm so scared to kill it. The performance seems good for now.....37 seconds is a far cry from the 53 I started off with!

What fan di you recommend I use on my northbirdge? How you get heatsinks to fit without the clips that are normally on a socket? Is there some kind of "thermal glue" out there?

Sorry for all the questions. The last machine I o/clocked was a P41500, and that was 4 years ago!

Basipooh · Post by **Basipooh** » 26 Oct 2005, 22:38

not sure bout the fan, looking for one myself.
Its practically impossible to burnout a pressie coz they have thermal throttling which makes the CPU skip cycles if it gets too hot (over 75 degrees roughly) so dont worry about that.

Try superpi with HT enabled now at ur new clockspeed im intrested to see what u wud get.

Basipooh · Post by **Basipooh** » 26 Oct 2005, 22:39

oh, ja thermal paste, get artic silver 5 if u wanna try anything else.

AlphA · Post by **AlphA** » 26 Oct 2005, 22:52

Ok, just rebooted and disabled HT....its a LOT slower...45 secs in Super pi!

I dont understand this! One thing I did notice is that only 50% of the CPU was being utilized when HT is enabled.

When I disable HT, the CPU is fully utilized (100%)

Thanks for the tip......I'll pick some up from Cyberdyne.....will be going there on Friday...

Basipooh · Post by **Basipooh** » 26 Oct 2005, 22:54

hmmm... do u have XP home or XP pro..

Coz if u have xp pro, ur cpu utilization graph will have 2 graphs which will add up to 100% or more.

XP home (or anything older) does not support HT and will leave ur cpu only 50% utilised. (while HT is enabled)

AlphA · Post by **AlphA** » 26 Oct 2005, 22:59

I use Win2k Pro SP4 on this machine... it does show 2 graphs when I have HT enabled...

I know its now using 100% of the CPU because the time is a lot slower than when I disable HT...

Also, if I do the test using HT on, my machine is still usable...When I disable HT and do the test, my machine is maxed out and pretty much useless until the test is over (proving that its REALLy using 100% - hence the good score of 37)

Basipooh · Post by **Basipooh** » 26 Oct 2005, 23:01

I reckon installing XP pro on ur machine will solve it. I have XP pro and theres no difference i score with HT on or off on my pc. I like HT on coz as u sed i can bench and do other things at the same time.

Obviously, it seems tha win2ks HT support is not that great.

AlphA · Post by **AlphA** » 26 Oct 2005, 23:10

I was afraid you would say that. Although, you may not be 100% correct.......I'm not sure... Check out the links below... these guys are mostly running WinXP

Read the third post from the bottom in this link http://forum.majorgeeks.com/archive/ind ... 67013.html

And check out

And one more for now

And, something on HT which I myself havent read yet

i cant access any of those links coz im capped and cannot access any sites out of SA till next month.

AlphA · Post by **AlphA** » 26 Oct 2005, 23:15

Oops....my bad...

Anyway, it was just a couple articles about HT being slower. Some of the benchmarks were done on machines running XP... Just wanted to point that to you

Whats your pi score with your HT disabled??

Another thing.....I only have a 300W PSU....could that be part of my problems?

There's pretty much nothing in my machine though.....just one stick of RAM (512MB), 1 HD, 1 DVD recorder and a PCI ISDN modem. Oh yes, and 2 case fans.

Basipooh · Post by **Basipooh** » 26 Oct 2005, 23:18

pi scored didnt change with HT on or off.
HT gives a very slight performance hit in games but im talking 0.5%.
and makes the system ALOT faster at multitasking and general snappyness.
I like it and prefer to leave it on..

This is just in my experience tho. ive had my HT pc since Jan.

AlphA · Post by **AlphA** » 26 Oct 2005, 23:19

Just read through one of my links... Thought you might find this quote interesting...

"'Finally, the last component that is required is an operating system that recognizes dual processors or HT technology. Intel indicates the Microsoft Windows 2000 and Windows XP are HT compatible operating systems."

Basipooh · Post by **Basipooh** » 26 Oct 2005, 23:20

2000 is compatible but that does not necesarilly mean its optimal!!

AlphA · Post by **AlphA** » 26 Oct 2005, 23:21

I guess so *sigh*

Post by **ryanrich** » 26 Oct 2005, 23:24

From personal experience I don't like using HT, we've had very bad experiences with it enabled on our server systems...

AlphA · Post by **AlphA** » 26 Oct 2005, 23:26

Ryanrich --> I've got an HT system for a few days, and I'm already disliking it.

One nice thing about it though is that my system idles a lot lower with HT enabled. Load times are very similar it seems, whether HT is on of disabled.

Me, personally, I'm not liking it at all!

Install XP, win2k is not cool

my mom has it on her pc and it makes it run sooooooooo slow!!

AlphA · Post by **AlphA** » 27 Oct 2005, 05:57

I dont own a licensed copy of WinXP. I actually run SuSE Linux ..... just bought the 64-Bit version of SuSE10 on DVD. The reason I have installed Win2K now is cos I just built the machine. There is lots of stress testing, temp monitoring and benchmarking apps for Windows. Once I have achieved my maaximum overclock and prove to myself that its stable......I will install SuSE10 64-bit and be happy once again

its an intel board... a D915GAG to be exact, cant download the bios update as i am not allowed to d/l from ftp sites... will d/l from my boss's machine however...

Wish i could overclock,i got an intel 945 express mobo,and there is no way in hell i can overclock it,

AlphA · Post by **AlphA** » 27 Oct 2005, 09:05

Thats why I steer clear of Intel M/B's .. No overclocking abilities!
