Sorry in advanced if this isn't in the correct section of the forum.
I recently received a free motherboard with a processor, so I decided to put something together that I could do a little gaming on. I was able to reuse some parts that I already have and I got her up and running with Windows 7 64bit.
Only problem is that games like Crysis and Call of Duty 4 will run fine for 10 minutes or so (with all settings set to lowest), and then after that they start to lag like crazy for about 5-10seconds, and then normal play for 30 seconds. and this just continues over and over.
I can even have the settings on COD4 on highest and Crysis on medium and they will run great until the lagging starts.
Depends on what settings you're running the 2 games on, if it's high then try taking them down, it may be straining the CPU too much and throttling it. 400W is not enough for that system tbh, especially on high loads for games, up it to a 650 or 700, corsair HX is the way to go.
Start it off at 1.4v. Also your PSU in terms of power output is perfectly fine for your system. I'd wager you machine doesn't even pull 300w at full load. BUT that doesn't mean your PSU isn't the problem, it can still be acting up.
Check you RAM too, maybe run memtest or something similar. The issue seems as if something is throttling or for some reason you computer is accessing the pagefile too frequently.
kk It was actually just the CPU. I downclocked it to 2Ghz (from the stock 3Ghz) and now everything is running fine.
I have the choice of1.400V, 1.425V, and 1.450V CPU voltage in the BIOS
and I can change the multiplier at increments of 0.5 starting at 5 and going to 15 (with a FSB of 200Mhz).
Of course I want the best performance out of my system. What would be the best way to proceed with upping the speed?
and I don't believe heat was ever an issue. PC probe never gave me anything higher than 50C (I checked it by using Alt-Tab during gameplay and during prime95). Hardware monitor gave similar results.
Vote for the PSU. That CPU pulls 125W stock, assuming you'd overclocked it at all your going to pull ridiculous amounts of power. Whatsmore, i recall reading somewhere that the 4870 pulls over 200w ( can push 250w ) stock. Initially you said your CPU Vcore was fluctuating as low as 1.17V, make sure you have "Cool & Quiet" disabled in the BIOS. Its a functionality that downclocks the frequency and reduces the voltages when CPU usage drops below a set level. That can affect your games as usage fluctuates wildly in game. The fact that reducing the frequency, and thus the power usage, seemed to provide a solution lends credence to it being a power supply issue.
I think I'm also going to flash the BIOS and see if that does anything.
How do I check if windows is accessing the pagefile too frequently, and what do I do about it if it is?
DO NOT flash the bios unless the new bios has a fix for the problem you are having. A failed flash can render your motherboard useless without a way to fix it.
Turn on the task manager, and then the performance monitor. Look at the graph for memory. It will have a number for hard page faults per minute. I doubt that you will see a meaningful number(>60/min) there, unless you are doing some heavy multitasking.
If the number is very high, the only good solution is to add RAM.
