Is my i7 870 underperforming?

(Overall Score (14182) Stock Intel Core i7 870)

Your CPU need to be reset to stock clock speeds then run your 3dMark score agian it should have a score somewhere around 14,182 for the stock Intel Core i7 870.

I would try:

1st: Turn off PC and take off side panel then remove battery off the motherboard and power cable off the PSU.
2nd: Then hold down the power button while the power plug is off and the battery is out.
3rd: Put everything back together and turn on, but don't change anything in the BIOS!
4th: Try to run 3dMark agian.
5th: Write down score or post on here.
6th: Restart computer and go into BIOS and start overclocking as long as your score is increasing you'll do fine.

When the score drops even by a little set it back down by however much you increased it.

I hope I helped you.

that score sounds about right, assuming you are not using an nvidia card.

systems with nvidia cards running Physx get considerably higher CPU scores (artificial inflation.) im fairly sure that your score is normal.

That score is on ATI 4870.

That does sound quite low to me. My 920 gets over 24k for a cpu score with HT on and a lil under 18k with HT off. Your 870 should be similar.

My old SLI rig:
MB: MSI K9N Diamond (AM2) PCI-E x16/x16
CPU: AMD Athlon64 X2 DualCore 6000+ 3.0Ghz CPU
RAM: Corsair Dominator TWIN2X DDR2 1066Mhz 4GB (2x2GB) CL5 (@ 800Mhz + CL4 timings)
GFX: 2x XFX Geforce 8800GTS 512MB 650M
OS: Windows 7 Ultimate 64 Bit
3DMark Vantage Score (Performance): P12350ish

My new SLI rig:
MB: Gigabyte GA-P55A-UD4 (1156) PCI-E x8/x8
CPU: Intel Core i7-860 2.8 Ghz
RAM: Corsair XMS3 DDR3 1600MHz 4GB (2x2GB) CL9
GFX: 2x XFX Geforce 8800GTS 512MB 650M
OS: Windows 7 Ultimate 64 Bit
3DMark Vantage Score (Performance): P13457 (GPU: 11044 - CPU: 39051)

Both system scores are with stock clock rates. Gotta say I'm happy with my i7-860 there. I can't fathom how your i7-870 performs that bad.

I'm sorry if you don't see me post here much anymore, but I'm having a hard time figuring out this problem so I'm going to post on some other threads on tomshardware and if I here a solution to your poblem I will post it here! I hope I helped in some way and I hope the good people on tomshardware can get you all your questions answered Jarmel.
