    Question Help with Pentium D 805 & GA P45-UD3L overclock.

    Hi again!

    Could anyone give me some advice on how to overclock my CPU? so far I've been able to get it to 3.66GHz, using the following settings, it's "stable", (I put that in brackets because I can play for 3-4 hours intensive games like Crysis, Borderlands, and such). It took me a while (applications crashing, system reboots, and when I was most sure of my settings, the PC rebooted while making a 7z file, LoL, but now it's perfectly fine), because I didn't want to make the Prime95, Memtest and such time & power consuming test, but if they're mandatory, I'll make them.

    Now, after a bit of history, here are the settings I'm currently using:

    Code:
    CPU = Intel Pentium D 805 *OEM* it has the multiplier locked to 20,
    Motherboard = EP45-UD3L, Revision 1.0
    BIOS Version = F5c
    Ram = A-data vitesta 1066+, http://www.adata.com.tw/downloadfile...GB(128Mx8).pdf
    on the physical RAM sticks, the timings are as follows: 5-5-5-15 2.1~2.3v

    You are running your memory at 732Mhz, did you know this?

    You may have better luck using "C" memory multipliers if you do run into issues. What I personally would do would be to use a lower CPU multi so you could use a higher FSB for the same speeds so you could run your ram faster, but that is all up to you. For example 11x333 then use 3.20B memory multiplier or possibly 3.33C

    You should also set your Driving Strength profile to 800 for each channel for now, if you run the ram at 1066 then set this to 1066 of course.

    The rest all looks ok to me

    I'm a little new in all this, because my previous Motherboard was a Nforce4, with an AMD 64 cpu, and kinda "did it everything by itself".

    I was trying to run the memory at that speed because of the "performance gain", I was previously on 200Mhz latch and some other multiplier that gave me 601MHz, or so, for the RAM, but one day I did change it for 266MHz latch, and ran the Win7 System Rating Test, and RAM scores went up by 0.2 points now it has 5.4 (with of curse, needing 2.1v) that's why I'm running them like that.

    As for the CPU, it was part of one of my older computers, and it's an OEM one, it has the CPU multipler locked, I'm afraid, I can't change those.

    The CPU itself has 533mhz FSB, for me to run the RAM @ 1066 (and according to the BIOS) I would need to have a 4GHz (200x20) speed, which I cannot achive, and I've been trying quite some time now.

    I'll take a look at the Driving Strenght profile and "C" multipler for now.

    Thanks for your time, and your quick respone, I hope this CPU could at least reach 3.8GHz in the future.

    Well I am new to it too kinda, since I have not used a Pentium D in many years. So forgive me if I did not advise much, it's hard to remember how those CPU's work

    It's good to hear you know what you are doing memory wise, I was just checking on that in case you did not know anything about it all.

    Locked CPU Multi? Is it a engineering sample? It should not have a locked multi unless it is. You can check with Everest if you are not sure, or tell me what you saw printed on the top of the CPU. If it said Engineering sample then it ws of course, or if it said confidential or had only random numbers and not the name of the CPU then it is.

    Ya I know about the CPU FSB, I have used them. Please do check with Everest you should be able to change your CPU multi, but maybe only to 12-20 or something like that though.

    In Everest you will find the answer here on Engineering Sample or not and Min/Max CPU Multi >>



    And here is a trial in this thread if you do not have it already >>

    When experimented with 200FSB and DDR-800 CAS 4 I was able to use tRD 3, bandwidth was about the same but latency much lower. Since you are not going to exceed 200MHz you can try and see if it works for you, or at least 4 (MemSet show 6 with Static tRead Value auto).
    You must have used the 3.33C multiplier but there is 4.00C also in the 200MHz Latch.

    Something is wrong with MemSet main screen, and it does not read the SPD correctly, see if the latest vers. 4.1 fix this.

    Thanks for bearing with me, it's not my intention to push you or anything like that, I respect your knowledge and thank you for trying to help me with my OC.

    Well, according to Everest, it's not an Engineering Sample, but I can't see any CPU Multiplier settings anywhere, then I went to google, and found out that:

    -Most Pentium D processors, have the CPU multipler locked, only Extreme versions may allow the change.
    -There's no workaround for it, some motherboard companies, have only achieved a lower Multplier, by setting the CPU in power saving mode, which, I can't turn on (I've been trying with CPU RightMark utility, as it shows those options)

    By the way, any B multiplier with lead to an unbootable system, I don't know why. So I've sticked with A & C, which I'm now testing to get the lowest latency and still mantaining the same speed & scores for the Windows System Rating.

    I'm afraid Memset 4.1, can't read them either, the odd thing is Everest & CPUz can, they're in the first post, pretty weird.

    Also, which setting changes the tREF? as I'm using 2855 when the Jeded#1 profile says 2080 (if I'm reading it properly).

    Maybe report this to Felix (MemSet creator) and send him the profile so he can see what is going on.

    There is no option in BIOS to change it.
    JEDEC profile#1 is for 266MHz and you are at 366MHz, it's fine.
    I see you set tRD 3, any improvements in memory bandwith/latency?

    I'll look into it.

    I see you set tRD 3, any improvements in memory bandwith/latency?
    the tRD 3 is result of using a 200MHz frequency latch for now.

    So, if I select the Frequency Latch at 266MHz, and the memory itself it's running at 366MHz, that's the real speed? What's the Freq. Latch Setting for? I'll have to read more about this.

    Well, the "Windows System Rating" went down by 0.1 (RAM was rated 5.4, but I don't trust it that much, before it went from 5.2 to 5.4, but it kinda stabilized with 2.1v, so it's now 5.3~5.4.

    Latency is lower now, 99.6ns ~ 100ns, compared to 116ns ~ 126ns, it used to report, but the reason I didn't use 200mhz latch it's that games using streamed textures (U3, Crysis, Borderlands) have a longer delay to show up the textures after loading. I start a map, finishes loading, but the textures are blurry, and take longer to show up properly (compared to 266MHz memory latch), which, if you ask me, it's weird.

    And it seems like running them any lower won't do any good if I don't use 3.33C (4.00C @ 200 Freq. Latch, won't boot), but then my RAM scores drop to 5.2 again.

    Guess I'll go back to re-tweak to get a lower latency.

    --
    here's a screen using the lowest settings available, and they look nice, at least the memory READ & latency are a bit nicer now.



    I'm having a headache now, lol...

    using:

    Code:
    (G)MCH Frequency Latch....................: 400MHZ
    System Memory Multiplier .................: AUTO (because any other setting won't "reach" more than 700 on the settings below)
    Memory Frequency (Mhz) ...................: 1066   732

    I doubt the Latch does anything realy but changing the available options for memory multiplier.
    The latch refer to FSB not memory frequency.

    With "them" being what? If it is timings you are refering to than of course the larger multiplier results in higher memory frequency which will need higher timings.

    Well the MCH Latch changes internal NB Freq's and timings, so even using the same memory multi throughput can be drastically different.

    Well you very well could be correct with your CPU multi, I just told you all that to be sure you did not think it was locked if it indeed was not. I have used a few pentium D's myself and they were unlocked, but they could have been ES's or extreme ones I don't remember.

    To really take advantage of your board and GFX Card you really should get a new CPU, are you saving up to do so? That CPU is bottlenecking your GFX Card badly and this is why your games are not playing properly.
