Asus P5E3 Premium Wi-fi-AP

[jeanjean15]

I had the same problem to pass the 400fsb until i found the right skews. The problem is that i don't know how to pick the best GTL's, nb skew and cpu skew I'm just trying lucky shots.

Atm i'm using GTL67/69, cpu 400ps, nb 200ps.
I can run prime 8h with no errors but sometimes i get 1 error after 8h30m. I tried to run that test and i can pass the test now and if i run it again i get an error dunno why. Anyway i think 8h is stable enough.
OCCT says stable...

After a lot of tests with this board , my conclusion is that the X48 chipset can't support a too high bandwidth with quadcore .

Try 5:8 ratio and relaxed timming instead of 1:2 ratio in order to decrease memory bandwith if you want be able to increase cpu frequency and get stable with prime95.

I'm back again with good results.
Here are my settings, at 3.6Ghz Finally STABLE.
I was running Prime 95 for 10 hours without any errors.

My System:
CPU: Intel QX9650 - batch L744B175
MOBO: ASUS P5E3 Premium Wi-Fi / Bios 0505

PSU: ENERMAX Galaxy 1000 Watt

My settings:
CPU Ratio = 8.0
FSB Strap = 333
FSB Freq = 450
PCIE Freq = 105
DRAM Freq = 1800
Command Rate = 1N
Timings = 8,8,8,22
DRAM Static Read Control = Disabled
DRAM Dynamic Write Control = Disabled
CPU Voltage = 1.12500 (Bios)
DRAM Voltage = 1.80
NB Voltage= 1.55
Load Line Calibration = Normal
CPU Spread Spectrum = Disabled
PCIE Spread Spectrum = Disabled
Memory Remap Feature = Enabled
Vanderpool Technology= disabled
All other settings is auto.

Hi,

I have very same configuration means QX9650, p5e3 deluxe wifi and sticks Corsair 4 GB DDR3 1800. After changing the settings I could boot 1st time but then from second time I could only get to splash screen on Asus Gate and then no matter if I try to enter BIOS or OS PC turns off!

I made a cold reset of CMOS and then make all changes again (as it was back to 133 MHZ in BIOS) but only left memory timings according to datasheet:
2N, 8,8,8,24. Exactly the same result. Can not boot 2nd time. Only splash screen. I am tired of dismantling PC and making CMOS reset. Please help!

Thank you.

CPU Voltage = 1.12500 (Bios)

Don't think you'll boot at 3600Mhz with that vcore...

[Razmatazz]

I'm assuming you mean ExpressGate. Disable it.

[Infa]

Okay now I did put CPU skew 400 and NB skew 200, Now it has gone 50 mins no error, just before i changed, it went 4 mins before it errored in Blend. now 40 with these changes thats sweet. you never think that one setting will help, but obviously it does things now im feeling "little" better with maa mommy board.
but still RE is the bigger brother, and he's tougher and harder hehe........ want to be friend with it :P

I was doing some P95 stability testing today and found it very easy for some reason to get 466FSB 1:1 stable. This did require CPU 1.33v set in bios.

Here's a screenshot. Its still running strong as I type this, no errors.

[nunor]

I just want 3.6 but don't know why with your oc profiles i always get a bsod on windows logo...

[deachus]

I just want 3.6 but don't know why with your oc profiles i always get a bsod on windows logo...

Probably because my settings are too tight for your Samsung IC's. Try using a higher PL like 8 or 9.

[nunor]

The PL on your profile was on auto and i think i tried to set it to 9 and use 8-8-8-21 timings even with an higher vdimm... bsod like always.

Nobody is going to be able to give you the exact settings for your hardware to run 450FSB stable. This is what I do to find stable settings:

1: Change one setting in Bios
2: Boot to MemTest x86 and run 3 passes
3: If error then go into bios and change one setting
4: Run MemTest again (If pass 3 times with no errors boot into windows)
5: Repeat over and over till you pass MemTest with correct settings
6: Boot into windows and run p95 Blend
7: If I get error I go into bios and change CPU/NB settings since mem was stable in Memtest
8: Repeat these steps over and over until you find stability at the FSB you want

This did not happen overnight for me, I have had this setup since late July and it's been getting better and better each week. That is after endless hours and hours of testing.

[nunor]

Passing memtest at 1800MHz don't avoid prime 5sec errors.

[Razmatazz]

Ditto that nunor. This means that your memory is capable of running at that speed but your system is not stable at that speed. I believe that the issue with running at that speed has to do with the bandwidth required. This will require tweaking NB voltage, GTLs, NB & CPU Skews, Pll, VTT, ect........Head spinning yet???

Take it easy and make small steps. If you're stable at FSB 400, then go to 410 and tweak that first and move up slowly one step at a time. As deachus has pointed out, it takes many hours of tweaking.

Many hours Razmatazz? Haha, I'm just messing with you. It has taken me hours and hours and hours compiled over 3 months.

You will get out of your setup what you put into it. The more time, testing and tweaking, the better results you will get. You must be determined!

I was not happy at all with the results I was getting the first month I had the setup assembled. But I was determined to figure it out and obtain the stable settings I wanted.

Nunor - I have a set of 2x1GB G.Skill D9GTS sticks for sale if you want them. You will most def. be able use my Profiles with them. I am keeping one kit for benching and I am selling one kit to put the money towards the CSX Diablo 2x2GB D9GTS sticks. I found a contact across the pond that will be shipping them to me Monday and they are confirmed D9GTS 2x2GB.

I think the ram is not the problem because i tried 3 ram sets (ocz platinum 1800, ocz reaperx 1333 and gskill hz 1600) and the oc problem is the same.. until 400fsb is ok, after that is a pain in the ass!

After lots of days spent in the last months trying to tweak this i found something stable at 425FSB. If i increase 5MHz i'll get an error on the first test... same story that happened when i passed from 400 to 425 but this time i'm not lucky to find the good settings :\

I know that GTL's depends on the vFSB but i don't know how to find the good values for them (in "ps"). Same story for the cb/nb skews, i'm just trying lucky shots but with no success til now.

I was trying to find the tightest 24/7 timings my sticks would run and heres were I'm at so far. After finding 8-6-7-19-2T stable I tried going tighter and using 1T which worked which was a surprise.

[Defratos]

I posted this in the OC section but doesn't look like anyone's got time to help, so I thought I'd give it a go here since this thread is dedicated to the same MB I have, Would appreciate ANY help or feedback, thanks.

Now take it easy on me I'm a nood when it comes to OC'ing which I'm looking into, I want to push my Q9450 from stock 2.66GHz to around 3.2GHz (I know it sounds low compared to most on this board) but I just wanted a bit more without raising temps too much.

I've got 4 of these OCZ DDR3 PC3 - 12800 memory ( http://www.newegg.com/Product/Produc...82E16820227320 ) but I wanted to find out what is the PC # for this memory? All I can find on this memory is PC3 but what exactly is that? is it PC3200, PC3200, PC3500 or PC3700?? and are am I right with the below settings for this card?

Effective speed: 1600 MHz
Operating Frequency: 800 MHz <----Is this correct?
Timing is: 7-7-7-24 <--- should be correct
Currently running @: 1.9v

also I've got a Q9450 @ stock 2.66 GHz

Effective FSB: 1333Mhz
Real FSB: 333MHz
Multiplier: 8
which gives me the sock CPU speed of 2.66MHz (Duh..)

my Motherboard is: Asus P5E3 Premium.

Now I've read the Noob's OC'ing guide:http://www.xtremesystems.org/forums/...ad.php?t=57148 But I think that this is a bit outdated (written in 2005) and I've also been going through the Q9450 Temp and setting thread: http://www.xtremesystems.org/forums/...182602&page=41 .

Now can someone give me a brief guide through as to how approach raising the CPU speed to around 3.2GHz? I've already played around with the settings for the memory in the BIOS to get the system running stable as it kept on freezing when I first got it, so I just changed the below settings from Auto to:

DRAM Voltage: 1.90
DRAM Frequency: DDR3-1600MHz
CAS# Latency: 7
RAS# to CAS# Delay: 7
RAS# PRE Time: 7
RAS ACT Time: 24

These were the recommended settings from OCZ ( a fellow Xtreme member helped me with this ) or else I would still be sitting with a very unstable system. Currently my system seems very stable and I just wanted an easy guide through as to what I'd change in the BIOS to increase the CPU speed. Should I take small incremental steps while raising the CPU or just increase it up to 3.2GHz all in one time.

I know this might sound a bit of a bore to most of you OC'ing whores (excuse the French) but reading soo many threads has helped me a lot but I think I've also read a lot of unnecessary info, which is why I'm looking to someone who'd be kind enough to explain a few of the basic steps needed to OC the CPU to get it running stable with the current memory I've got.

Thanks in advance for any feedback given

Oh one more thing my OS is Windws Vista Ultimate x64bit

ok ok, after reading a little bit more on this thread I've got a few questions. With the above hardware I plan on doing the following:

Increasing the FSB from 333 to 400 with a multiplier of 8 (stock multiplier setting) should effectively give me 3.2GHz correct?

this would mean running at 4 x 400 = 1600MHz correct? If so would my memory be able to cope with this as the effective speed is 1600MHz but the operating frequency is 800MHz? sorry if this is a dumb question.

Now my question is what voltages would you guys recommend to start with? to see how stable the system would be?
CPU Voltage
CPU GTL Voltage Ref (0/2) and (1/3)
CPU PLL Voltage
FSB Termination Voltage
NB Voltage
NB GTL frequency
SB Voltage
DRAM Voltage I will keep at 1.90v (as specified by OCZ, I might try running it on 1.8v and see if it'll work)

and would I have to change the CPU Ratio setting or FSB Frequency?

Any other changes you could recommend or any settings you'd recommend I keep on auto would greatly appreciated

I can run 400*8 with all stock voltages. At 400FSB your ram will run at 1600MHz (the 800MHz you see you have to multiply by 2 to find the real speed)

FSB Strap=333
CPU Voltage: 1.25v (make sure u set Load Line Calibration=Normal, you don't need all that voltage but it won't hurt because will be the same as stock voltage)
CPU GTL Voltage Ref (0/2) and (1/3) = Auto
CPU PLL Voltage = 1.50
FSB Termination Voltage = 1.10
NB Voltage = 1.25
NB GTL frequency = Auto
SB Voltage = Auto
DRAM Voltage: Set the timings and voltage according to ocz site and set the Refresh Cycle Time to 60 manually.

The refresh cycle time of 60 may not work for his IC's, might be to tight. This will depend on the type of IC's on those OCZ sticks. There is a very good thread over at OCZ Forum in regards to his sticks and the P5E3 Premium board. Tony OCZ has also posted bios profiles for QUAD's, P5E3 Premium and different OCZ memory.

Just a suggestion

Thanks for tha added info guys, just a slight clarification I would set the FSB Strap to NB @ 333 and not 400MHz?

and where would I find the option to set the load line calibration to normal?

and you're right Deachus I have seen the thread over at OCZ conserning my RAM and it is loaded with info so I'm just taking my time in reading all of it. Thanks once again.

What exactly does IC's stand for?

Do you happen to know what the stock voltages are? because in the BIOS it doesn't show and in windows it only shows my Vcore Temp which @ stock was 1.14v. But I have no idea what the stock NB voltages are or for that matter what the other stock voltages were at?

any decent programs out there that can read the voltages to other components other than the Vcore? I.e. any programs that can read what my stock NB v is at?

[nunor]

You don't need fsb strap 400 to run at 400fsb. It's like a timing, if you are overclocking the fsb a lot you'll probably need to relax the nb to find the stability. In other words, strap 333 is faster than 400.

LLC option should at the bottom of the same page.

I don't know if ocz mems can't handle 60 tRFC, i just said that because i had 2 sets of ocz's and the board didn't like them. I advise you to run memtest and check if you get errors.

IC's are the integrated circuits that you memory uses. Even the same ram model can have different IC's. You can only check that if you remove the heatsink but you'll probably void your warranty.

The stock voltages are the voltages that i posted before. You can check in the bios when you select an option, on the right side will show you the information about the stock values, normally are the lowest values after Auto. You can't check voltages in windows with any program because the board doesn't got that feature.

PS: if you are using 8GB os ram you may need extra NB voltage.

Hi guys, this thread has been looking dead for a while so why not liven' it up a little, here goes:

I've managed to get my Q9450 stable @ 3.2Ghz, this wasn't too difficult. But now I'm trying to get my 4GB OCZ 1600 Reapers to work at their stock speed. Before I managed to get the system stable by using 1300Mhz but now I've bumped this up to 1600Mhz which is the stock RAM speed for the OCZs that I have. Now where I'm having trouble is I can run 2 hours of OCCT completely stable, but 10min after the test the computer will freeze, sometimes I've been able to use it for 1.5hrs after the OCCT test and then it'll freeze, so I'm not sure which settings I would have to change to get the system more stable. Below are my settings which gets me through the OCCT stability test, also I've noticed that even though the computer will pass OCCT it refuses to pass Prime without errors. I always get an error around 10-15min into the test usually on Core 4, but I have had it give me errors on core 1 and 3 as well. So I'm a bit lost to what this is indicating. If anyone could suggest any changes to my bios to get the system more stable I'd really appreciate it thanks.

CPU Ratio: 8.0
FSB Strap: 333
FSB Freq: 400
PCIE Freq: 100
DRAM Freq: 1601
DRAM Command rate: 2N
Timings: 7-7-7-24 (stock timings)
DRAM CLK Skew A: Norm
DRAM CLK Skew B: Norm
Dynamic Read & Write: Disabled
Ai Clock twister: Auto
Ai Transaction Booster: Auto
CPU Voltage: 1.29375
CPU PLL Voltage: 1.54
FSB Termination Voltage: 1.30
DRAM Voltage: 1.90 (stock voltage)
NB Voltage: 1.45-1.47
NB GTL frequency: 0.61
SB Voltage: Auto

LLC: Normal
CPU SS: Disabled
PCIE SS: Disabled

Anything I haven't listed will be in Auto. So if anyone could give me a helping hand to getting the system more stable (i.e. pass Prime error free for a few hours, or not freeze after OCCT 2 hr stability test) I would really appreciate it, thanks.

I would say you need to change the following settings.

CPU PLL Voltage: 1.6
FSB Termination Voltage: 1.32-1.36
DRAM Voltage: This should be fine but try going up to 2.0v
NB Voltage: 1.58v - 1.65v
NB GTL frequency: 0.67

I would say the most important setting you need to change is your vNB especially running 4GB of ram.

Here are some screenshots after many many hours of stability testing over the past 3-4 days. I could not get stable past 350FSB running 4x1GB D9GTS so I ordered a Mushkin 2x2GB D9GTS kit which should be arriving any day. I will be doing some extensive testing this weekend with those sticks and will post my results and settings. I would also suggest you follow the steps below to confirm your system is stable. I have come to find out passing the OCCT 2 hour test means nothing and does not confirm your system is stable. Try this out:

1: Run Memtest86 Test 5 before booting into OS. If you pass test 5 three or four times with no errors then boot into windows
2: Run HCI Windows Memtest and let it run for 20 minutes but you should run it overnight to confirm no errors
3: Run LinX 50 runs or 100 runs and see if you get any errors
4: Run Prime95 overnight and see if you pass that

If you have done all 4 steps and passed everything with no errors then you can say your system is stable. I found LinX errors after 25 runs and had to up my vTT one notch and passed everything after making that change. Yes this process takes a while but is the best way to confirm your CPU and memory are stable.
