My Custom Build PC currently Hosts the Following:

i7 3930K @ 3.8 GHZ, 8GB x 4 @ 2133MHZ Kingston Hyper X, Rampage 4 Extreme Mother Board, 2 x GTX 680 EVGA SC, 1500 Watts PSU Thermal Take, Corsair H100 CPU Cooler, Corsair 800D Case, Windows 7 64 Bit, 512Gbps SSD Primary Corsair and 2TB x 3 Western Digital HDD.

The issue i face is as follows: If i try and overclock the CPU to 4.2 from the bios and the FSB Reads 5000MHZ then i am not able to push the ram more than 1333MHZ, in this case the mem tweak reads 666Mhz and the score is 43454.

But when i push the ram to 999 which is 1998Mhz on Mem Tweak, then the cpu false back to 3.8. In this case the Mem Tweak Score on ram shows 54354.

My Question is what is better for gaming overclocked processor or overclocked ram.

In case of my graphic cards which are already superclocked GTX 680's running in SLI Mode, @ power target to full 132% using Evga Precision X and keep the GPU Boost at 50%+ and MEM Boost 50%+ it works great

But when i try to keep the power target 132%+ and increase the GPU Boost to +180% and MEM Boost to +425% the drivers crash and restart

I have seen people doing this on line, just wanted to know what am i doing wrong

thanks for assistance

regards

OCing the CPU will benefit you far more than OCing the RAM. As for trying to achieve an OC on your GPU that you saw someone else do, there's a catch to that.

It's very difficult to OC 2 of what appear to be the exact same things (such as 2 GTX 680 EVGA SCs) with the exact same results. All chips ship (GPU, CPU, etc. Doesn't matter) with imperfections. What happens is, when you try to OC those 2 things which are the exact same brand and model, one will usually end up with a better overall OC result than the other. You may not be able to reach the same clockrate, for example. Or, if you do reach the same clockrate, you may find one them needs slightly more voltage than the other, or one gives off more heat than the other. The...

The higher the OC you're trying to accomplish, the less likely it is you just happen to have 2 GPUs just a good.

It really is just luck of the draw.

thank you for the reply, gave me a better understanding. i guess i will stick to overclocking the cpu

The only thing i still dont get is BF4 and COD Ghosts wont run on Ultra on my specs. Is coz they are build for newer generation of cards

Really? That's...odd. Your system could handle ultra no problem. If there was an ultra+1 setting, you could do that too lol. Even with your GPUs at stock speed, ultra shouldn't be a problem.

Well i have read there are still some performance bugs that need to be ironed out with both of those games. Hopefully soon you'll be good to go.

Hahahahah. That was also my reaction when i could not play BF4 and COD Ghosts on ultra for more than 30 mins. The Graphic Drivers would just crash. However i was able to play Saint Rows 4 and Batman Arkham Origins on ultra and it was a perfect life. I guess some performance bugs as you have pointed out, guess will have to wait it out for an update.

Do you think i should go for a higher card like 690, coz lot of the upcoming games are demanding for higher Memory, 2GB DDR5 not upto it anymore or its just issue specific to COD-G and BF4

Anyways thank you for addressing my issue. Appreciate the help :D

The 690 has 2x more memory than a 680, but there's a catch to that too :p

Basically a 690 works exactly the same as a 2 680s in SLI, they just add the bridge chip onto the 690. Also the 690's clocks are lower so moving to that would actually reduce your performance. Not sure what resolution you're gaming at, but 1200p or less and 2GB is plenty. The performance loss at 1440p is very minor, but noticeable at 1600p and up. Or if you're using a 3 monitor surround, i can see needing 3GB per GPU even at 1080p. Otherwise though, 2GB works.

well i am using the asus 27inch 3d Led Back Lit monitor, which is 1920 x 1080 resolution at 120Hz refresh rate

i agree the base clock of the 680 is unmatched till date. Yesterday i saw an EVGA GTX 780 TI w/ACX Cooler Super Clocked which was showing me a similar base clock @ 1006 MHz but a higher boost clock @ 1072 MHz. This was the only card having the boost clock higher than a 680. Secondly the Cuda Core and Texture fill rate was significantly higher than the 680's i have

I guess waiting and having these 2 cards would be better than going for 690's. Plus i can add 1 or 2 going 3 way or 4 ways incase required. This is the link where i found the card, yet to me be released i guess
