I just swapped out my two 128 sticks with 256 sticks. 1gig now. At 175mhz I believe. . More points hooray
Yay 1GB thats always good :good: However, just to tell you that Folding@home won't use your 1GB unless you've set it to do so Also there won't be that much improvement from having 768MB to 1024MB perhaps you could get some 600 Pointers now you've got your 2800+ - you never know
Due to massive instabilities, I've set clocks at 166. Only screws up under massive applications and games (BSOD). Would 1gig of ram@133mhz (133 FSB also) be faster than 768mb RAM@175mhz (175 FSB)?
1GB @ 133MHz compared to 768MB @ 175MHz The 768MB would be "faster", as having more[/] memory does not increase speeds.. just means you have more[/] memory. Ninja, i really hope your NOT using memory dividers, because unless you're overclocking your CPU by a good 400MHz you won't see a performance increase but a decrease. And i presume that your memory is PC2100? (133MHz=DDR266) by default, or is it PC2700 (166MHz=DDR266)?
I have a 512 stick of pc2700. 2 256mb sticks of what I think are pc2100. EDIT-Oh, and no I'm not using memory dividers. Always at 1:1
Folding utilises memory speed more than the "amount", the "amount" of memory doesn't really matter, however the "speed" does. Folding @ home loves 512MB + of fast memory. In your case once you've reached 175MHz - the reason your getting instability is because your computer's PC2100 (133MHz/DDR266) is being overclocked To Far. Personally i would sell ALL your memory and order 1GB GeIL Value PC3200 (£60 here in the UK). check these links out: http://www.chiefvalue.com/app/productdetails.asp?submit=search&item=20-144-310&ATT=&CMP= http://www.chiefvalue.com/app/productdetails.asp?submit=search&item=20-144-309&ATT=&CMP= Ideally if you REALLY want good memory, you want memory that can run @ very low timings, as this considerably increases memory bandwidth and efficiency of the CPU. For example, Fred is getting 400-800 Point WU's, because: 1. He has 1GB of memory 2. It's Dual Channel (128Bit) (single = 64Bit) 3. it runs @ 2-2-2-5 Latency This means he can run BIG WU's at a low latency, because Folding @ Home or anything thats purely CPU intensive is immediately effected by the speed / bandwidth of your memory, hence the faster your memory / latency the better. Having 512MB (2x256MB) of 2-2-2-5 would get you more points than having 4GB Dual Channel CAS3 memory. Ninja, download CPU-Z 1.27 and post a screeny of your SPD / CPU
Or even better: http://www.newegg.com/app/viewProductDesc.asp?description=20-156-020&depa=1 $100 for Dual Channel 1GB and for that price its got good timings Cas2.5 so i presume it'll be 2.5-4-4-8
I'm getting quite a large amount of money soon, definately gonna get that one you posted in the link I was lookin at it about 14 hours earlier!
Ninja if you want some Very good memory, get some Corsair XL/Crucial BallisitiX/Geil Ultra-X/OCZ Platinum. And definately get PC3200, think about it, if you get some PC3200 thats rated to run 2.5-4-4-8 @ PC3200(200MHz FSB) and your only running @ 175 / 180 or something you can lower those timings even tighter, to 2.5-3-3-5 or something, i doubt anything lower would be possible as its not TCCD but still. Also remember you'll standa better chance of overclocking if you increase your DDR Voltage to the max your motherboard can withstand (2.8V Usually) as youll get better overclocks or atleast a more stable pc.
Its a shame you've got 512MB OCZ @ PC2700 as its good memory, your other memory is quite obviously generic as CPU-Z cant even get a reading of the manufacturer or chip.
Yeah the OCZ has been a champ for me, very reliable, low temps. It was on sale and I didn't have overclocking on my mind at all. The other Rams were free. Just parts unused by a friend. I snatched him up and gave him my old rams http://www.newegg.com/app/ViewProductDesc.asp?description=20-156-022&depa=1 $20 more and you get pc3500 lolz
Why bother getting PC3500? - Your not going to overclock to 216MHz realistically are you? and if you get some reasonably good PC3200 (Kingmax are fine for this), you can easily expect to reach 220-230MHz. However if you are going to be overclocking to 216-230MHz you'd want the PC3500 as it'll be capable of lower timings @ higher speeds.
The easiest & safest way to find your max overclock is to do this: Lower your Multiplier from stock to say 1, 2 lower. (example: my AMD64 3200+ has a multi of 10x - i lowered mine to 8x). Now, keep increasing your FSB in 5MHz increments until you get abit of instability, then increase your Vcore by 0.025V. Keep increasing until you reach another unstable OC & up your Vcore by 0.025V again.. (keep repeating this until you reach what you believe to be your max OC). Now at this stage, if you've already overclocked past your memories Stock Speed (ie if you have PC3200 overclocking would be Over 200MHz FSB) you'll need to start increasing the VDimm in 0.05V increases. Bare in mind that your memory depending on manufacturer will have a limitation on max running Vdimm. Most can safely go upto 2.8V (almost all major branded memory can).
Depending on your motherboard, you may not be able to change the Multiplier, if you don't have the feature already, i doubt you'll have the capability.
no multiplier change. I've seen 3rd party performance BIOS updates though. Might try them. If all else fails, I'll get an Abit.
I'd worry about getting some good memory first. Get some tight timing memory (2-2-2-5) and then get a new motherboard / or both.. Abit AN7
