Artic silver, cooling overclocking question

I currently got Artic silver 3 , a thermalright slk800 hsf with a 80mm 50cfm fan.

My P4 2.4c is at 3.6ghz. I can run Prime95 for about 15 mins before it fail at that speed.

If I were to upgrade my current cooling solution with :

Artic silver 5, Thermalright SP-947 or SP94 with a 92mm fan

Would it be more stable by not failing in Prime 95.
I could try it and see for myself, but im limited on cash and I want to know before I spend the $ for it.
 
i dont really see a point in it. you have a good heatsink with good paste. your processor is overclocked to a good speed. its not like there are any real world aplications that will run ur cpu at full load for 15 straight hours. benchmarks are just that, benchmarks.
 
camay123, not necessarily. I've currently got my 2.4c @ 3.54ghz 24hr prime95 stable, and thats as far as I can take it without lockups, crashes and prime95 failures. My specs are:

Abit IS7
CPU @ 1.7v
RAM @ 2.8v
1GB Mushkin PC3200 2-3-2-7
Koolance Exos watercooling system
Arctic Silver 5

My previous HSF was a Swiftech MCX4000/Arctic Silver 3 with a Vantec 80mm tornado that was loud as hell but kept everything running fairly cool. Now with this old setup I was also able to run at 3.54ghz stable, but it was loud of course. If I were to run at 3.6 prime95 would fail within a few minutes. Even now, watercooled with the EXOS the temps are a few degrees cooler, much quieter, but I'm still in the same overclocking rut. I can not run at 3.6 stable for more than a few minutes without a failure. Upping the voltage didn't help either. I'm sure there's something keeping me back, whether its the motherboard, the ram... or maybe that's all the CPU will do?

My point is, swapping out your HSF and slapping some AS5 on there probably wont make a difference. I didn't in my case. And as an FYI, I like to run prime95 for 24 hours just to make sure my system is as stable as possible.
 
Im mainly asking because of previous experience.

when I had an Athlon 1200mhz I would run it at 1500mhz with a FOP32 hsf, but when I changed to an SK6 w/ 60mm fan I was able to run it at 1575mhz completly stable. A minor increase, but still an increase in stability.
 
Are your temps good under full load? If it's ok then you don't need to change your setup. Try lowering the fsb a little to get your system stable.

I get 52c under load. My goal is really to get it at 3.6ghz, so I dont want to lower fsb. At 3.6ghz it pass the 6hr test of Hot cpu tester.
 
At 3.6ghz @ 1.7v bios ; 1.65v actual It run Prime95 for 10mins
At 3.6ghz @ 1.8v bios ; 1.75v actual it runs Prime95 for 1hr+
I wish my mobo would do 1.75v Bios : 1.70v actual, I dont like it with the voltage that high.

2Fresh : No water. I just sold my WC stuff. Im trying to keep it on AIR
 
NOt being a dick here....but why are you worried then? If you are sable in everything else? That is a great oc, I would be content.
