Value in OCing memory

[supermaughan]

1. Is it worth while to overclock memory if I can't overclock my CPU? (Corsair CM3X2G1600C9DHX, DDR3 1600 9-9-9-24 1.8v)
2. Is it a good idea to OC intergrated GPU? (My mobo has settings to increase gpu clock, defaults to 500Mhz)
3. Not an overclocking question but how much Memory should I give my Intergrated Graphics? (128Mb, 256Mb, 512Mb, or 880Mb)

mobo = Asus M4A785TD-V EVO (ATI Radeon 4200, 128Mb sideport memory)
CPU = Athlon II X4 630
memory = 4 (2 x 2Gb) Corsair CM3X2G1600C9DHX, DDR3 1600(OC) 9-9-9-24 1.8v
OS = Vista Home Premium 64bit

I've tryed to OC but I'm having very little success. I can only achieve about 5% on my CPU. So I'm giving up for a while. If anyone is familiare with this board and an Athlon II X4 CPU, I could use some advice. Also, can someone tell me what the Test Mode option is for CPU Overclocking?

Overclocking memory would not give much performance boost. . . If you are going to overclock cpu remember to increase voltage too or it will just reboot and tell u that the overclock failed, I had the same struggle on my asus mobo. an fsb of 235 and overvoltage of +100mv should be fine. Vista requires atleast 1GB ram to operate and reserve 2GB for games, otherwise you can assign as much as you have to spare! ! !

I don't think it's the voltage that is keeping me from overclocking. If I leave everythinging set to auto and just increase the fsb from 200 to 220, it works. If I try 221, no boot. If I manually set the Memory speed to 400Mhz, I can get to 250 (haven't tried much more because prime95 was heating my CPU up to 66C with stock cooler.)

Memory defaults to 533Mhz.

I tried setting the CPU voltage to say 1.5 1.55 but still no luck.

Because you are OCing a AMD system so if you overclock your ram you will still get performance increase even not by much.your system is unlike those intel cpu who run on FSB so bandwidth increase is restricted in their case.

I've seen noticeable speed increases while encoding video on an Intel Fsb run system.

That being said, your talking about a small percent of the program titles that people run on a daily basis.

Also in my experience, overclocking memory can introduce more stability problems then overclocking the cpu/fsb, so make sure you know what your doing.

Is it worth underclocking the memory so that I can overclock the fsb? What about the GPU? I will be using this computer for Photoshop and AVCHD editing. Not to many games until I get a discrete GPU. I would like to try a few older titles that I could never run before on my Athlon XP 2900+ Barton.

to enable you to get higher OC you should lower multipliers for memory and certainly the CPU if you are looking to acheive higher overall system performance rather than just CPU alone.i dont think overclocking the GPU has a dramatic affect on the photoshop experience.because on a 9600GT on default clock will do all the fancy stuff just fine.but increase it if you game you should see about 5-10% gain at most.
