Hello everyone,

I am new to the overclocking game and would greatly appreciate any advice from you veterans.

My i7 860's factory setting is 2.80ghz, but I understand that it can be pushed much further than this. Unfortunately, the RAM seems to be causing a bottleneck as the FSB (set via SetFSB due to having a BIOS-locked Dell) on the CPU cannot surpass 145 without causing stability issues.

I stumbled across the below site whilst trying to figure out a solution, and it seems this gentleman managed to overclock the same CPU in an identical Dell to 4ghz.

He resolved the problem by switching from PC3-10600(DDR3-1333) to PC3-8500(DDR3-1066) enabling him to set his CPU's FSB to 4ghz.

From my limited research I have discovered that PC3-10600 is 'faster' than PC3-8500 so this question arose in my mind:

Is my original PC with 2.8ghz i7 and 6GB PC3-10600(DDR3-1333) better or worse than my intended overclocked PC with 4ghz i7 and 8GB PC3-8500(DDR3-1066)?
 
Probably not noticeably, and the extra MHz from the cpu would likely counteract anything lost. Must be some weird ratio issue that causes that problem.
 
Thanks for your reply, but I suppose I should have been a bit more specific.

Is it worth the effort in buying the new PC3-8500 memory so that I can do the CPU overlclock or will I not notice much difference?

I understand I am only asking for your gut instinct on this one due to my lack of knowledge :)
 
If you do cpu intensive stuff then the Mhz increase would be beneficial, in day to day use (internet, stuff loading, Office etc..) you would see just about zero improvement though.
 
For overclocking, always start with the cpu, and keep the ram to it's minimum operational freq for the cpu clock. Then, you can push the CPU knowing the ram isn''t causing any problems. Then, when your happy with the CPU clock, work on the ram, start by manually setting the correct timings in the bios, then pushing the clock speed up. A lot of it depends on ram type/make/speed, motherboard and processor, so even with identical parts to Joe Public, you could attain a completely different overclock.

Welcome to Overclockers ;)
 
Problem is, hes using software overclocking as the advanced BIOS options that might allow for overclocking is locked out by DELL
