Thank you, thank you. That works

For those running 4X1gb sticks:

After the reccomended settings from Ace this board seems stable now. I'm running 4X1gb crucial ballistix pc6400 at 5-5-5-12 with a 2.150 from bios and on page 131 I've just changed what Ace told me. PWR temp area doesnt exceed 60C on full load cause I have quite good airflow in the case.

A friend (Gomar) on the greek overclocking forum "thelab" did the vmod to reduce the vcore drop. 1.55 on bios gave 1.55 on full load with a quad. Before the mod he had a drop of 0.1 volts!!! (1.60 gave 1.49 on full load)

If anyone wants more details about this I can ask him to post pics

Hey, could you list these settings? My RMA'd RAM comes in tomorrow.

Also, I have an "unknown device" in the device manager I can't figure out what is. It says it's on the PCI bus, although it can't be on the physical PCI bus as I only have my soundcard and a wifi card in there. It pops up both in Vista and XP. What is it?

Please do ask your friend to post some pics. Did he do Johnny Bravo's Vdroop mod? Which resisitor value did he use?

Thanks

Pci-e 2.0 is compatible with 1.1, no problem between p35 and new gpus.

http://en.wikipedia.org/wiki/PCI_Express

PCI Express 2.0

PCI-SIG announced the availability of the PCI Express Base 2.0 specification on 15 January 2007.[2] PCIe 2.0 doubles the bus standard's bandwidth from 2.5 Gbit/s to 5 Gbit/s, meaning a x32 connector can transfer data at up to 16 GB/s in each direction. PCIe 2.0 is still compatible with PCIe 1.1, so older cards will still be able to work in machines with this new version.

The PCI-SIG also said PCIe 2.0 also features improvements to the point-to-point data transfer protocol and its software architecture.[3]

In June 2007 Intel released the specification of the P35 chipset which does not support PCIe 2.0 only PCIe 1.1.[4] Some people may be confused by the P35 block diagram[5] which states the Intel P35 has a PCIe x16 graphics link (8 GB/s) and 6 PCIe x1 links (500 MB/s each), for simple verification one can view the P965 block diagram which shows the same number of lanes and bandwidth but was released before PCIe 2.0 was finalized. Intel's first PCIe 2.0 capable chipset is the X38 and boards are already shipping from various vendors (Abit, Asus, Gigabyte) as of October 21, 2007.[6] AMD starts supporting PCIe 2.0 from its RD700 chipset series. NVIDIA has revealed that the MCP72 will be their first PCIe 2.0 equipped chipset.[7]

Thanks

yes, he did johny bravo's mod. He used a variable resistor of 1kohm set to 680ohms at the beggining and then he started lowering the resistance value of the trimer until it was stable. He doesnt know for sure whats the value now of the variable resistor set at... Have in mind this was done with a quad. Settings may be a bit different with a c2d since the drop isnt that much with a dual core

There's something weird going on with my system. It just hard-locks out of nowhere. Today I wasn't even running prime, I was watching a video on google video and it just froze completely. It's so weird when prime and memtest seems to be perfectly stable - except when prime decides to hard-lock as well. I've clocked down a bit to see, but this is definitely weird.

Couple of days ago i flashed my IP35-E with 1.3 bios, and i had some strange problems with my system, stange freezeup and so on. Then i realize from some reason my memoryvoltage was locked to 1.93, and increasing this from bios didnt help at all, it was still locked to 1.93. Reflashing didnt help, so i flashed 1.2 and now it works. I hope that ABIT can fix this

Thanks Daytime Dreamer
I will post results when I get the mod done.

have you installed the INF Intel drivers after you installed your windows OS...most likely that is the SMbus controller.

this is not to chase you away but did you know there is a separate IP35-E thread.

Yeah I have, both in Vista and XP. I used the newest ones available at intel.com. Really wondering what it could be.

Hey guys,

I have the following setup which i have built for a customer at work...

Intel Core 2 Extreme QX6850
Abit IP35-PRO (Latest bios)
Chaintech Apogee GT PC8500 4x1gb (Link)
Antec Atlas (550w PSU) Link
Samsung 320GB SATAII
Samsung 20x SATA DVD-RW

OK, i have installed windows with 4gb and it was all fine...
i then reboot after i finished installing all the latest drivers etc and i the computer freezes after about ~2mins.

i then decide to run a memtest with the 4gb, and it errors like crazy after about 30mins..

I have

- upped the volts from 1.8-2.1v
- changed timings to 5-5-5-12
- ram is running below spec (ddr812)
- upped mch to 1.29v
- tested 2x1gb kits for hours (both kits test fine by themselves)


I have no idea wat to do, this is urgent and im all outta ideas

[jagt]

uGuru??

I installed it a few days ago and I haven't checked since then. But I checked now, and lo and behold! The unknown device is gone. Haha, thanks though.

Urg...that sucks.
Have you tried to memtest each of the DIMMs individually? If not, I would - using the same DIMM slot each time.
If they all pass individually, next I'd start to populate the additional slots one-by-one until you find the where the errors are coming from.

Also, what version of Windows is installed on it?

yep tried individual sticks aswell ,

i have installed Winxp Pro SP2

the device won't disappear until the next or 2nd re-start...that is my experience with that bugger.

[AstroCreep]

32-bit or 64-bit Windows? Reason I ask is that you won't be able to utilize all 4GB due to Windows only being able to allocate 4GB of addressable memory space (which includes video memory).

Now when testing each stick, did you also test each DIMM slot? It might not be the sticks.
What I would do is test each DIMM in the first DIMM slot (is it listed as 0 or 1? I don't remember with RAM...). As long as each DIMM tests okay in that one slot, you know that slot is good.
Next, as long as each DIMM tests okay, I'd take one DIMM and test it in the next DIMM slot (still only using one DIMM at a time). As long as that DIMM passes, move on to the third, and if that one passes, move onto the fourth.
If all four DIMM slots work okay being populated singly, next step is to populate them in pairs; start off with the first "Dual-Channel" set (1 & 3, IIRC) and test them. If they pass, add one to DIMM slot 2. If it passes, add the fouth. If it doesn't pass here, yank out DIMM 2 and see how 1, 3, and 4 run together.

I know, there might be a lot to it, but this is the route I'd try to isolate them.

Good luck!

first of all...win xp sp2 32 bit does not support 4G's of memory.

second: you need to up the vdimm to about 2.25 to 2.3v

third: change your dram timming to 5-5-5-18(tRAS..or higher) and "tRC" to 42(or higher)

fourth: mch needs to be at 1.4x voltage minimum.

Ok, thanks alot for that info, i'll give it a try today..

its winXP pro sp2 32bit, and yeh i understand that 32bit doesnt support 4gb memory, the problem is that this is all being tested in dos (memtest)

first of all...win xp sp2 32 bit does not support 4G's of memory.

second: you need to up the vdimm to about 2.25 to 2.3v

third: change your dram timming to 5-5-5-18(tRAS..or higher) and "tRC" to 42(or higher)

fourth: mch needs to be at 1.4x voltage minimum.

ok i will try those settings today, thanks alot guys

ok i tried these settings and different tras and trc but still the same errors,

bak to the supplier these ram sticks go..

Which test# gave you errors?

[NiSMo]

Which test# gave you errors?

umm its the test that is on the ultimate boot cd... dunno which that is :S

[maxwedge]

Oh, I don't know that one and was thinking memtest86+
btw, if you want 4gb of ram on this board I'd be looking at two 2gb sticks and not four 1gb.
