The Maximus Formula Thread - Help/OCing/Guide/Rampage conversion

[Grnfinger]

What were temps of cores? I think mine was idling 32ish and max was 50 when I cold air benched it, hotter made me drop core more. I got better results from clocking memry first than going after core because once it gets the heatsink so hot memory artifacts.. Heres a post its in.

My cores are like 67c+ on load, if you touch the back of the heatsink its actually to hot to leave your finger on for more than a few seconds.
Emailed the etailer about changing my order for a block instock and it would be easier to sell a kidney on the black market than to change my order, it piss's me off.
Maybe I'll let the card cool and test just ram clocks leaving the core's at stock not even run them at the factory OC settings.

Thanks for the link, off to read it now

Now this is interesting. Under Orthos loads, (one of) my CPU core goes up to 65C even in Everest with the default TjMax of 100C, which Intel states (although there are compelling arguments it may be 95C). The CPU itself sometimes goes up to just under 65C, and the other core tops out around 60C. This is at 4.05GHz. At 4.275GHz, add ~5C to each.

I've long expected my CPU to be running much cooler than it's being reported as. I've lapped it, switched from a Freezer 7 Pro to a Xigmatech HDT s1283 (yes, I applied thermal paste correctly), and have great case airflow (Stacker 830SE with many fans). All of these efforts gave minimal or no improvement in temperatures, yet, the sensors aren't stuck. If I overclock, they go up, and if I underclock, they go way down. I simply think the CPU itself or motherboard sensors are way off.

I also think this because I always see others saying they have the same CPU with an weaker cooler, a non-lapped CPU, and comparable case cooling, and they get idle temperatures in the 20s, and loads under Orthos for the cores no higher than 45C. How, then, is mine running that much warmer, or is it really?

Get this. With the temperatures you listed above, you say it's too hot to touch. I can touch the base of the heatpipes on the cooler, and remember, the heatpipes are HDT touching the CPU itself, and I can not only hold my finger there at these supposed 65C+ (70C at 4.2GHz wasn't much warmer) temperatures, but it's barely even warm. My Northbriudge, by contrast, typically runs ~45C, and the heatpipe between it and the Soutbridge is much warmer, almost too hot to keep a touch on, but not quite.

Would I be safe then, to assume I can basically "ignore temperatures" and push it further? I got my E8400 the day after launch (January 21st was the first day Newegg had them in), and the batch number is in the signature in case it matters, and I remember these early ones had temperature issues. I'm thinking I got either I got one of them, or the motherboard just has really sensitive sensors.

I was referring to my 4870X2 gpu core NOT cpu

Most 8400 have stuck temps sensors, everyone argues over the tjmax so its really a matter of how comfortable are you with the way everything runs.
You seem to have investigated your problem, so maybe trying 3 or 4 different apps to check temps, then take teh average and run with that?
Dont rely on anything from Asus for temps, they coudnt code a screen saver

Ah, I must have missed that. Either way, regardless of if it's a CPU or GPU, if something is running at 65C-70C, I shouldn't be able to hold my touch there on the heatpipe less than an inch away from where said heatpipe is touching the source of the heat and it only feel slightly warm, right? If I stick my hand inside my case in front of the CPU fan, I feel alot of cool ambient air from the fans. It can't be an ambient problem.

Most programs report the same thing. Either they give results as though the TjMax were 100C (Everest), or 95C (Core Temp, Real Temp, etc.).

My point is that, A) for what I've attempted to keep it cool, this seems too high, B) others with less colling preparation get better results with the same CPU at the same speed, and C) I've touched it and it's not as warm as my Northbridge heatpipe.

Also, my sensors aren't stuck. They move both ways. They just seem way, way off.

Is it a huge benefit to do the rampage conversion on the Maximus Formula. Just debating it right now. Be interesting to try it if I knew it would also be stable.

I've been curious for to get more detailed feedback myself. In over a year of teh hack, I still cant get any clear cut daily user feedback as to its functions in Sleep and Hibernate and on the 5:6 CPU:RAM divider?

Also I realized the RAM I asked about was not available and just now found out it is shipping out tomorrow so I can find out for myself now. I ordered the OCZ Flex EX PC2-9600 in the 2x2g kit and may try the PC3-16000 on my other X48 set.

Anybody else running newer rated DDR1200 on x38?

I've posted here before with my problem, and today I got back to testing again.

For some reason whenever I overclock and Prime95 the whole thing Core 0 seems fine with it but core 1 stops after a while (when using separate affinities). When I assign both Cores to Prime95 the whole thing stops right after a few seconds (same goes for OCCT, same script anyway)

My temps are perfectly fine 47-50 degrees. Another interesting note here is that Core 0 (altough not assigned) gets hotter than Core 1, about 2-3 degrees.

I'm currently running my rig at:
8*500 = 4GHz (E8400 C0) 1.45v, VID 1.225 (yes I know that's ridiculous)
1:2 = 1000MHz CL5 (OCZ FlexXLC PC2-6400 CL3) (2.3v)

I'm running these rather high voltages to make sure I'm having enough juice on there. The temps are just fine.

I am to say that there's something wrong with this processor, or at least a core of it.


While posting I am running Prime95 on Core 1. After two tests Worker 2 gave up due to a false rounding of the processor.
Worker 1 is still running.


Worker 1 failed after test 8

ASUS coding a screen saver that showed your mobo sensor info..

I think the latest Everest beta is showing my temps correctly now, before it would always be around 10c too much.
