I have an nForce2 ultra 400 chipset that's getting a bit long in the tooth on it's current configuration.
I'm currently running a Thorton core (late barton) XP2800+ cpu, overclocked a fair bit from it's stock 166mhz fsb speed to 188mhz. It's been running fine and stable at that for some time now with no heat issues on the standard AMD boxed HSF.
The final upgrade I'm thinking about before pensioning off this rig, is to get an XP3200+ cpu which runs on the 200mhz FSB speed instead of 166mhz.
At the moment, a new 64bit, socket 939 nForce4 ultra, "venice" CPU and quality PCIe graphics are just going to have to wait due to financial contsraints.
Now, I realise that I'm not going to gain that much FSB speed from my current overclocked configuration, unless of course the XP3200+ allows me to make a further overclock without spending a small fortune on a cooling solution.
The 3200+ runs at a stock speed of 2.2ghz, my current 2800+ is clocked at 2.35ghz and running as cool as it does at stock speed.
Benchmarking with SiSoftSandra shows my CPU result comfortably in excess of a stock 3200+.
However, benchmarks show my PC's memory bandwidth is not quite on par with a stock 3200+ based rig, and this I attribute to the slower FSB speed I am on.
My RAM is 2 x 512mb PC3500 Kingmax modules, and though they don't have excellent latency, they should handle a bit of an overclock with a 3200+ fitted on a 400mhz FSB. (or will they? )
From what I've read, the 32 bit barton's don't like going over 2.4 ghz, so I'm apparently very close to the silicons limit already.
I guess my question is, is it worth forking out the cash for the 3200+ and will that piece of silicon offer me further overclocking potential on air cooling, with a view to increasing my bandwidth towards the 3ghz/sec barrier, or is this just pie in the sky and should I hang out for 6 months until I can scrape up the dough for a new 64bit upgrade? Or is there another economical solution to boost this 32 bit platform?
