If anybody is on air, tell me if you can get over 279 fsb. I seem to hit a wall there, with two diff CPUs. I know the CPU and ram can go higher. It seems the NB voltage is holding me back, or there is too much voltage to spread around. I am at 1.60 VCORE, 2.0 VAGP and 2.9 VDIMM. One CPU has done 279 max on other boards though, so I can't complain.
I put a much stronger 40 mm fan on the Tiger1, but no diff. So it's not the temps.
I'm gonna try the rev. 1.2 to see if I can go higher.
I was running 3dmark and prime at 285 with 1.55vcore, which was more like 1.5vcore, 1.7vagp, and 3.22vdim. This proc isn't too good either...I expected it to top out at 3.4, so I was surprised it went higher with the stock pos.
This mobo appeared to be doa, then it seemed like I fixed it, then it looked like it had died, now it is working again, and hopefully it stays taht way :cool:
I was wondering if you guys are noticing realy long boot up times? When I first power it on it probably takes 15 seconds before video turns on, and when I reboot the video goes idle for about 5-10 seconds before it starts to boot back up. Anyone else have that? Both of my boards did this, but I think the first one booted a little bit faster.
Yeah, the board does that. Sheepishly boots up. You have to be patient. Sometimes when a board does that it is resetting defaults, but the Epox always holds it's settings.
I tell you one thing though, the board rarely fails to boot with any ram I've tried on it. At worse you can get into Memtest and see errors showing up. But a lot of boards won't post at all when you get carried away with the ram.
I noticed a long boot time on my board also but I dont think it was 15 seconds, more like 5 before I got that little beep to indicate that it was POST'ing.
Long POST times here as well, and long HDD detection time as well, but it's OK, I like it never the less. Mine is rev. 1.2 BTW.
And one more thing, if you cut power to the PSU, the POST time will be even longer, the first time I thought I fried something because the video wasn't starting at all.
how long did it go before it finally posted? That might be what mine did the first few times I tried to boot. Does it see to hang on c5?Quote:

Nope, didn't hang at all, took longer but didn't hang. I was used to 8RDA+ which got to POST really fast, and that's why I got scared at first, but then I got used to the long post times.
With the latest BIOS, the bootup seems to pause longer at HD drive detection, I think because some Epox boards have problems with USB Zip drive detection.
Yeah, sometimes my 1.1 board takes maybe 10 sec to boot, particularly after you change ram or the CPU.
But I got a lot of SD/CW boards that boot real fast but are slow in benchmarks!:p:
Them be the brakes.
You guys know how to read the 3.3v rail w/ mbm? It's reporting the vdimm for me. Also, can you read the NB temp through it too?
Strange how you see many other motherboards being reviewed all the time, but not this one.
Some good info here guys keep it up!:thumbsup:
hey guys, received my 4pca3+ rev 2.00, began the overclocking :) and had to up Vagp to get it stable as I increased the FSB.
so, my question: which Voltage do you consider as a maximum for Vagp? I mean, how does this voltage influence the gfx-card? do I have to understand it as some kind of mobo chipset voltage increment increasing gfx-card stability or overall stability?
well, someone in this thread uses 2V Vagp, any suggestions?
What does the 2 options under the ram timings do? Are these for PAT and is it best to leave them auto/enabled/disabled? Also, Epox states in the list of updates for latest bios "Improved "Aggressive_Memory_Mode" memory bandwidth when the item set on "MAX"." I don't even see an aggressive memory mode to set to max, only SPD or manual ?
I have asked about Aggressive_Memory_Mode about 10 times in this thread, and in every other 4pca3+ thread I have ever seen, and my best geuss is that it was meant to be placed as a change in the 4pda2+ bios revision being that it is in the 4pda2+ bios.
The 2 settings under the timings are for pat, and it would be best performance wise if they were enabled, but they might hinder your oc. I was able to have them and HT enabled at my max oc without any problems, and it helped my 3dmark and s-sandra scores by a little.
Got a sl6wr cpu 2.4c, will do some testing today.:D
I didn't see any option in the bios for HT ?Quote:

It is one of the top setting under "advanced bios options"
Ahh, I see it now. Skipped right over it, but it was enabled anyway.
*Update* Damn, I don't know what the culprit is but something is justr really odd here. Yesterday I could do a full run of 3dmark at 3.6ghz, 5:4, tightest timings. Today, I can't even boot into windows w/ out getting a BSOD much less run 3dmark unless I complete slacken the timings. It's not the memory itself, because I tried 2 different sets and it's the same w/ both. I did also have a problem w/ 3dmark crashing today at any cpu or mem speed. I had to uninstall/reinstall to get it to run again. What's happened? Did some part of the OS get corrupted? If that's the case, I don't understand why the mem timings would have any effect... This little system is giving me a headache...
Do a reinstall or the cpu may be dying too much juice.:(
I'm wondering about that SNDS thing now. Sheesh, I never even went above 1.65 vcore and this is w/ water. I can't even run 3dmark at 3.3 anymore. I've never seen so many bluescreens in my life, 3dmark just BSOD's or crashes to desktop, and I loaded UT2k3 just to try another 3d intensive prog and it crashes after about 10 mins w/ a page fault error. Now that would indicate a ram problem but w/ 3 different sets, that's almost impossible. The video card might explain the crashing to desktop but not the constant BSOD's. So that leaves some problem w/ the mobo or the cpu. Grrr....
Check for condensation, I know of someone who just experienced this exact same thing and there was some water under the pins.
It's only plain water w/ room temp air so condensation would be impossible unless there was a leak. It's also been running 3dmark fine for the last 30 mins at default speeds.
wow soul...that realy stinks. have you tried reinstalling the os?
I am gonna get a fresh install on my setup tomorrow when I put my prommy on. This time I will remember to load ghost or drive image!
Can you get your hands on another cpu to try out? Sounds like it is probably the mobo and not the cpu.
I am realy annoyed by this mobo, just something about it...I think I might pick up a p4c800-e. I could get the vdim/droop/3.3v mods done in 30 minutes. I am gonna see how the board does under the prommy tomorrow before I decide though.
