945 vs 950

[guppie]

What is the difference between these two CPUs? Besides an $80 difference? Thinking of getting the 945 - will this work in my mobo?

The 945's don't have virtualization technology. From what I've read it's used very little and you won't find any performance drops vs. the 950. The big plus is they are either C1 or D0 stepping so they run much cooler. That's why I chose the 945 and they had it on sale for $155 at the egg. And yes it will work with your mobo with a newer bios revision.

I have seen these cpu's on sale in forums and find myself wondering if I would see any real world difference between them and the D805 at 4ghz assuming I got at least that clocking the 945 to that speed. What a good OC on a 945?

[bignick]

Well I to had an 805 and the performance difference in gaming was small at the same clocks. It is faster at video editing but my main concern was heat and the 805 is a blow torch. My 945 does 4400Mhz benchable and 4255 everyday stable. My 805 did 4160Mhz benchable and 4000Mhz everyday. I think my 945 is being held back by my mobo and I have a new P5B-Deluxe here stairing at me that I'm putting in this evening. I think you would be wasting your money on any other 8xx/9xx cpu because you will be FSB limited with your Nvidia chipset mobo. I have built a couple and they usually hit a wall @230FSB. You'll need more than that to beat the performance of your 805.

[Nandro]

What are you going to do with your current MB? Is that the 945 chipset? Just wondering as I never considered the 945 chipset for OC'ing, then again people told me my board would stink and its pretty stable at 4ghz.

[bignick]

Yes it is a 945 chipset and it is a very good clocker. I have had it to 275FSB and I have seen them go to 300FSB with a 920. Your 4Ghz OC is fine because you are only running at 200Mhz FSB. Your chipset will crapout @230FSB. I will be selling my P5LD2 very soon.

Yes it will work woth your mobo. I had same mobo and CPU, and it clocks well. Its a hot running Proc when it comes to OC'ing, so you need good cooling if you want to see hight Clock Speeds.

Show us some results I've never seen that chipset clock worth anything? He would have to get to 250FSB to make any difference over his 805. And the 945 C1/D0 is an ice cube compaired to a similar clocked 805. He would have no problems cooling a 9xx series chip because he already cools his 805 with no problem.

Listen to bignick here, he is correct. You want the highest multiplier and performance for your dollar when sellecting a CPU for a NV chipset motherboard. The 805D is a very good choice with the 20 multi. The only other CPU I would suggest to someone owning a NV chipset motherboard would be a celeron, but your 805D already outperforms those.

[Nandro]

Actually I may be trading my board for the P5N-SLI even swap, and selling my D805, and picking up a c2d. Even if it dosent clock well at all its a good temp upgrade with minimal investment moving me in the right direction.

[bignick]

Good move Nandro, even at stock speeds C2D is faster than a mildly clocked Pentium D. Even at 4400Mhz my CPU scores in 3Dmark 06' are about the same as a C2D@2400Mhz.

[greenmaji]

I was actually thinking that once the single core C2D's come out that there might be something for C2D compatable SLI boards (that are out now, who knows how the 6X0's will overclock) with high multiplier.

For those who have are familiar with this MB/CPU setup, can someone please help me out? I have another thread going elsewhere, but for some reason, my system is completely unstable when gaming (at stock, too).

I can burn DVDs and surf the internet and play videos and multitask until I'm blue in the face, but when it comes to gaming, this system SUCKS - I don't get it.

I've already eliminated "audio" as being the problem. Changed drivers and even changed from onboard to SB Live card, now I'm back to onboard audio.

I've already eliminated "heat" as being the problem. Case fully open with A/C room temp at 74 and no OC whatsoever. Temps: CPU < 42, MB < 36, GPU <46. Temp history monitors don't show anything unusual or high.

I've already eliminated not enough "RAM" as problem. I recently upgraded from 2x512MB to 4x512MB. All the same sticks. I thought this would resolve the problem for sure, especially in BF2 - NOPE!

I've also eliminated "PSU" as being problem. I'm using Asus PC Probe II and I keep my voltages, temps and fan speed monitors up all the time. I also have all the alerts setup for anything greater than a 10% variance.

Lastly, I've been using Riva Tuner to monitor the video card properties. I don't remember all the settings, but there are like 6 graphs that display data history for clock, core, fan, etc... - all within normal limits (basically all the graphs show a FLAT linear graph - which is good).

BF2 starts to freeze up after about 30 minutes for 20-30 intervals. Marvel Ultimate Alliance same thing. Andd, believe it or not, Diablo II does the same exact thing! Diablo II! I think the requirements are like PII/128MB RAM/any video card... My buddies and I decided to go retro with an old game - still lots of fun.

Can someone please help me out!

I'm about to just reformat the entire drive and start from scratch, but since I've almost eliminated most hardware, what else gives? I'm convinced its the video card for some reason. Not always, but usually, when the GPU fan kicks in, the freezing starts - I say this because you can't mistake that sound of a GPU fan whirling up!

This system shouldn't be behaving like this. It's driving me crazy!
