Do these L2 Read/Write/Copy/Latency values look alright to you? These are on a Q9550 E0 i grabbed on the weekend. PL8 @ 415 x 8.5 on my DFI X48 board.

I'm a bit uncertain of the Write and Latency mostly. I don't know whether the latency should be that bad as I've never noticed it being that low on a 45nm chip, but maybe it was for all i know!

Anyway just let me know what you think when you get a chance to have a look. If in your experience they look alright I won't worry about it, want to determine whether its because of larger 6mb cache and heavier cost to access, or some kind of cache coherency issue my chip has!
Your L2 looks similar to mine.... my Q6600's L2 ran way faster.

Goal: 4GHz using the max multiplier of 8.5 and run ram at 1:1.
system specs:
Bios listed below

Xeon X3360 (Q9550) C1 water cooled with a stock fuzion v2 along with EK northbridge wb, laing D5 @ speed 5, and PA120.3 in one loop. Prime temps are 58C, LinX are 67C, northbridge temp is about 30C.

second loop is EK mosfet wb, 2 EK FC-R600 HD 2900XT crossfire, laing D5 @ speed 5, and PA120.3. The south bridge is heatsinked with a low profile copper sink, it stays in the high 30C.

Video cards are a mismatched crossfire of HD2900XT 1GB and HD2900XT 512mb, both water cooled. Blue screens happen with or without crossfire on.

Ram is 2X2GB GSkill F2-8800CL5GBPI (DDR2 1100) in the blue slots, Vista 64bit Ultimate SP1 all patched up. Jmicron controller is disabled, all sata AHCI installed. Power supply is a Silverstone OP-1000 1Kw. The motherboard is a X48 Rampage Formula.

So the problem is windows blue screens saying "A clock interrupt was not received on a secondary processor within an allocated time" or "General hardware fault". This has been going on for months, and thanks to this thred, it usually happens once or twice a day now. The information about AGTL+ bus signaling, GTL ref, bios 803, cpu clock skew, and Zuckers BIOS, decreased blue screens alot.

Memtest can run all day without errors, and processor has primed for 6 hours no errors, no blue screens. The blue screens very rarely occure under heavy load from gaming or priming, only once that I can remember. They occur during idle desktop, internet browsing, and word documents. Never had any issues during windows load screen.

The CMOS was cleared befor and after flashing the bios, and profiles where re-entered and saved by hand.

Load line calibration is enabled, and tested fine. CPUZ and Everest show no Vcore fluctuations between idle and load. The Vcore stays at 1.360v all the time no matter the load. The board was vdroop pencil moded and sealed by tape during inital building.

NB voltage has been up to 1.73v, SB 1.5v to 1.55v, PL 10 and 9, ai clock twister, all GTL's that fit have been tested, with no improvement and returned to as stated below.

Anyone have any input on settings or experience with thies blue screens?
If the GTL ref are kept within 0.8 to 1.0, is the 1.4 volt max safe FSB termination voltage still valid for long term daily use?
I also get that BSOD from time to time, however I bumped my core voltage up a bit and have yet to see that error again.
