I seemed to have hit a FSB wall. I get 4.15GHz(13x319) and it passes Prime95 for an hour with temps only low 50's. as soon as I go 13x320 it won't post at all and just beeps at be and resets itself at default clocks of 13x200. I even tried lowering the multiplier slowly down to x6 and still no post. I was hoping there is a trick to get a little more, or maybe a setting I overlooked.

Here's my BIOS settings:

Code:

*** GigaByte GA-EP45-UD3R BIOS F9 *** Robust Graphics Booster: Auto Cpu Clock Ratio: 13.0 *** Clock Chip Control *** CPU Host Clock Control: Enabled CPU Host Frequency(MHz): 319 PCI Express Frequency(MHz): 100 C.I.A.2: Disabled *** Advanced Clock Control *** CPU Clock Drive: 800mV PCI Express Clock Drive: 900mV CPU Clock Skew: 0ps MCH Clock Skew: 0ps *** DRAM Performance Mode *** Performance Enhance: Turbo (G)MCH Frequency Latch: 266MHz System Memory Multiplier (spd): 3.00A DRAM Timing Selectable (spd): Manual *** Standard Timing Control *** CAS Latency Time: 6 tRCD: 6 tRP: 6 tRAS: 18 *** Advanced Timing Control *** tRRD: Auto tWTR: Auto Twr: Auto tRFC: Auto tRTP: Auto Command Rate (CMD): Auto >>>Channel A: All Auto >>>Channel B: All Auto *** Motherboard Voltage Control *** >>>CPU Load-Line Calibration: Enabled CPU Vcore: 1.37500V CPU Termination: 1.3600 CPU PLL: 1.570V CPU Reference: 0.886 >>>MCH/ICH MCH Core: 1.300V MCH Reference: 0.901 MCH/DRAM Reference: Normal ICH I/O: Normal ICH Core: Normal >>>DRAM DRAM Voltage: 2.200 DRAM Termination: Normal Channel A Reference: Normal Channel B Reference: Normal *** Advanced BIOS Features *** C1E: Disabled EIST: Disabled

I also tried setting (G)MCH to 333 too see if the next boot strap would help and nothing at x6 multiplier as well.

Thanks for any help

Mark, with those voltages you can probably run 8x500 instead. Might need more MCH for it (1.34) and you will have to ajust refs. Also, set you (G)MCH Latch to Auto and pick you ram multiplier. Set your Static tRead (Performance Level) to 9 and maybe even 8 if 9 is stable.

Sorry to trouble everyone but first of all, thanks for the info. I started reading and realized it would take me forever to get through it. I have this mobo, an E8500, Xigmatech Dark Knight, 2x2gb Corsair PC8500 1066 Dominator memory, 4870 1GB, 2x500GB WD Black in Raid 0, 1x1TB WD Black for storage, SATA LG burner, and a 950 watt quad 12v rail 85+ Thermaltake Black Widow modular PSU. I have a Lian Li with 2 intake in front, 1 exhast in rear, 1 exhaust on top. I'm wondering what the best bios setup would be for my setup. I want a nice daily OC. I don't need to get 4.5 unless I can. I've been running Vista 64 but I got Windows 7 for $29 as a student so I picked up the 2x500GB because I broke one of my raptors SATA connectors :/ I'm doing a fresh install soon so I figured it would be a great time to OC this gaming rig. I don't mind lapping the cpu and HS if it will make a huge differance. I'm mainly after a decent daily OC. Template would be awesome :)

Kind Regards,

Brian

What is the best latest BIOS for overclocking 65nm quads?

I am having problems getting anything past 400FSB on ym EP45C-UD3R. I'm not a noob to clocking but so far this board sucks. Any tips?

Try settng just your cpu voltage, mch voltage and memory voltage first. This board really doesn't like having alll its setting set at once and this is my guess about what you are doing wrong. Then you go through one by one and try to tweak your gtls and other setings. This board does not, suck! :p:

Are there any particular memory dividers and nb straps I should avoid? Any particular settings I should disable for overclocking? Dram write training? also where is performance level in the bios?

really don't get it...I had my p5q at 512fsb stable and I'm having trouble getting over 400 with this one :/

Post your hardware first, I could help you out.

I am also using the F5F beta bios...unfortunately I can't revert back to the F4 as I can't find it anywhere.

F5F isn't a bad bios. Give me a second.

ok thanks, I appreciate it. Was looking forward to some high FSB clocks with this board...and I know my chip is decent as it did 4.2GHz on my blackops with only 1.275V

thanks so much for that, I'll give it a shot and comment back later

Yea, it's a starting block, let us know.

Edit: I'm sure 4.00D is 1:1. It might be something else; just choose anything from 1600 and above based on your ram's capabilities. TRRD or PL 8 should be the right setting too. I'm just not too familiar with OCZ ram.

Gurusan, try messing with ur ref voltages (CPU & MCH), on my q6600 i needed 0.80v on mch ref to get past 400fsb, although i wouldn't think u would need to do that on a 45nm dualie...

Also, for 400FSB u should use the 4.00A (266) strap, i found anything above that (333/400 straps) would make the RAM unstable and need +dimm. Although importantly - for 450FSB+ the 333 strap works wonders...

I have never been able to get my system to run right with tweaking the clock skews. What does that do slow the north bridge talking speed down a little? If it does wouldn't then then in turn slow down your performance a litte? Or does it just keep things in sync? Might be a dumb question, sorry if it is.

Yeah, it's about sync, only useful in high fsb situations though, not for breaking 400 fsb, with a dual core.

Well, I can't even get the damned thing to boot into windows at 450FSB.

Also those settings look quite wild compared to my old P5Q Deluxe....I was 512fsb stable (4.6GHz) with 1.20FSB term, and .655 GTL....also only used 1.32 nbvoltage

So.....I tried every single memory ratio at 450FSB and nothing boots at all! :/

It can't be the board though, I'm sure it's something else. you're overlooking. Give me some time and we'll figure this out.

Edit:
Using the same settings from my other post: If you haven't yet, disable TURBO and use 3.33B PL8, (or 9, if it doesn't boot first time) I think that'll give you DDR3 1333. Also, what vdimm are you giving the ram?

Gurusan, have u tried ur RAM modules on any other P45 DDR3 board? And are they low voltage or the 1.9v?
10-31-2009, 01:23 PM

Thanks for the help everyone, turns out I wasn't giving enough MCH voltage and the GTL ref was wrong. Now using 1.38V MCH and .750 MCH REF..and 1.28VTT
....clocked at 500x8, 2GHZ cl8

Ahh good to know mate, i knew it was MCH ref :)

Get clocking :up:

yup my mistake was clocking it like an asus board....the p5q really is different by miles

I had the P5Q Deluxe before this board so I know exactly what you are talking about.

Will i7 memory 1600MHz C7 1.65v works fine with the EP45T-UD3R?
