Llano in the house... (as Charged :-) )

[gkiing]

This may be a dumb question, but I'm using my old CRT monitor on my Llano setup, and when I up the FSB, the monitor refresh rates go all screwy and it doesn't work. I'm assuming that the PCIX bus speeds, memory controller, everything are locked to the CPU fsb? How can I deal with this? I'm using the A6-3650 and GA-A75m-UD2H

VGA drops out around 120MHz BCLK on Llano.
Use DVI with VGA-DVI adapter instead.

better gpu in the 3870k, but from my testing and others, the average on air cooling is about ~3600mhz cpu ~900mhz gpu. (for 3870k)

similar results to what i got out of my gpu's for performance, Much lower than what i was getting out of my 3850, was getting 1100+ out of that chip :\ will probably spend more time on it this weekend, since i got about 50l of ln2 on hand.

I'm having trouble with the Realtek 8111E Gigabit on my Biostar TA75A+. After BCLK 125, it just craps out and does not establish any connection within Windows. Thats really too bad because I can boot as high as 155-160FSB. I have tried combinations of increasing APU-NB, FCH voltage, vcore.... nothing helps the Ethernet controller boot higher. Any ideas?

On my 3670k, my best Linpack IBT stable results are 3.69GHz. The best practical combination of speed/voltage is at 3.6GHz. I can post all day at 3.7, 3.8, 3.9GHz, but no shot at all in getting it stable with the cooling I am using (Antec 620 Kuhler). Anything higher than 3.6GHz, the voltage needed goes up by a ton. Results are pretty much in line with what the rest of you guys are getting. Idle Power consumption is great due to gating, but at Load its almost as bad as an x6

[gkiing]

I haven't experienced any ethernet problems, but i haven't gotten the FSB (can I call it that anymore... lol) above 110 with the crappy Patriot Gamer 2 memory I have.

Can anyone explain the different voltages on Llano boards and how they affect the CPU/GPU? Those strange NB/FCH? Commonly used voltage settings?

[Miwo]

This is from Dino / Gigabyte: A75 OC Guide
http://91.121.148.119/downloads/PDF/...5_OC_Guide.pdf

Problem is this is mostly for Gigabyte, other boards like mine (Biostar TA75A+) tend to relabel things / called differently

[Miwo]

you can always try to use slower memory dividers to get higher fsb speeds

[gkiing]

Thanks for the guide, yes i'm going to use dividers, I'm just trying to figure out how to hook up my CRT to a DVI port while retaining ATI dual graphics.. since the onboard DVI is digital only. I can't use the CRT for high fsb, it just doesn't go on. I've ordered a new LCD monitor but it won't be here for a week or so.

[gkiing]

Also.. does anyone know how to overclock your discrete video card (i have a 6670) when in ATI Dual graphics mode? The sliders in the vision control center for oc'ing dissapear when you select dual graphics.

I've found that my vga seems to drop out as low as 105??

Sadly don't have any other spare cables with me, awaiting a HDMI I picked up just so I can have some fun clocking my new llano setup.
I'm pretty pleased with it so far, although performance in games is a little meh, very jumpy framerates if nothing else, even in stuff like tf2 with ultra low quality configs....
Saw massive improvements going from 1333 CAS9, to now 1860 CAS8. Now need to clock the inegrated graphics to see if I could use it as a daily driver

[gkiing]

For sure, I am finding llano depends heavily on memory bandwidth. Did you look at the gigabyte OC guide? What cooler are you using?

[GeorgeStorm]

Cooling it with a 240 rad with coolermaster sickleflows.
What monitoring software do people recommend? Since I can't find one that gives actual temps for the cpu..... (ones I normally use give me random/negative/really high figures which change on their own, regardless of what the cpu is doing....)

[TsunamiJuan]

Some chips will drop out earlier than others for the bclk, I have had a couple that will drop network controller as low as 110fsb, Others that dont drop the network controller till around 170fsb. It does not seem to be mother board related as the same results where shown across three different motherboards from three different manufacturers.

If your Having problems pushing past 105fsb, the first place you should be looking is the ram and ram timings, after check voltages and cooling obviously. Usually memory is the cuplrit here.

[GeorgeStorm]

Well, as I said, I lose vga out at 105, and so can't push it any further since I can't see what's on screen :P
Once my hdmi cable arrives I'll be able to try pushing it further, and I always drop my ram when clocking to begin with (in this case I'd drop it one divider, down to 1600s atleast)

[TsunamiJuan]

Ahh yes, these boards no likey the vga, They dont like add in video cards much either at higher bclks, which is part of makes it so interesting when you start overclocking them. You'll reach a point once you get your video problem fixxed that the ram comment will come into play. Since Llanos and ram go hand in hand.

[gkiing]

So what's the best ram for llano? This patriot stuff I have is killing me.

[Alex-Ro]

good psc or bbse

Hi,
I wrote a private message to @The Stilt as I saw he is very active in the thread about ASUS motherboard bios issues but I will write it here too.
I am looking for the latest updated bios for ASUS F1A75-V EVO board because I am not happy with the latest official bios' OC combined with 3870K. All the links in the thread aren't active anymore so I can't download the modded bioses.

Moreover, I have a strange problem with the memory. I haven't tried for maximum overclock but even on default voltage 3.4-3.5GHz is bootable and runs in Windows (haven't tried stability as well). The mobo has no problem to reach refference clock up to 140 and the GPU stands as well (don't know how to reduce the multiplier of the GPU so this is around the limit for the reference multiplier). The strange thing comes when trying to overclock the memory which is 2x4GB Geil Evo Corsa 2133 CL10. Everything above 1950MHz is an instant crash in all sort of ref. clock frequencies (below 110, below 130, above 140). I tried all sorts of timing and varied the memory voltage from 1.5(default) up to 1.7V but without success. I kept the cpu below 3GHz when trying this and left the GPU at the lowest multiplyer I can set - 6. The APU is currently with the box cooler but I wanted to make some tests to be sure that its worth it to buy a cooler. SATA is on IDE mode and the monitor is connected via DVI-D and latest bios 1601. Tried everything down to 0603 with the same outcome.
I am quite confused with the EFI bios as I've used a lot of Gigabyte, Asus and MSI mobos but with the classic approach in bios representation. The things I would like to ask are - do I have to rise any voltage (either NB, SB, memory controller) in order to get 2133MHz running and generally what would be an appropriate setup for the gpu and the memory, the cpu is pretty straightforward with the unlocked multiplier. I have experience with AM2 and AM2+ systems but have never overclocked DDR3 memory nor Llano, so some suggestions about good combinations(suitable for highest performance with the APU) of memory frequencies and timings would be great as well.

Thank you in advance.
P.S. After the latest tests even 1600 CL9 is not stable... Either I am missing someting or the memory should be replaced for faulty. I was hoping that the memory will be with Hyper BFR chips and will OC good.
P.P.S. I solved the problem with the memory so far, the problem was in the secondary timings. After loosing them a bit 2300 CL9 is bootable. Will try more OC when I have time.

Hey guys,

I'm currently benching a llano cpu with the GA-A75-UD4H board and I'm trying to get the vcore above the default 1.8 volts. Any ideas if there is a voltmod or a software trick to increase the voltages? Northbridge voltage could need more boost too.

TsunamiJuan, you successfully did some kind of mod for your result here: http://hwbot.org/submission/2244256
Please help a fellow overclocker out and share some details.

Thanks!

Ok, I found the solution. It's really easy, maybe too easy.

There is a slider in Easy Tune 6, that is not limited at 1.8 volts. I will let you know, if it's working. CPU-Z is positive, but who knows.

[Miwo]

I'm using 30nm Samsung Low Profile 1.35v sticks with my Llano. I have 4x4GB running right now at 1680MHz @ 7-8-7-22 2T. Could not get it stable with 1T at these timings. 1T is stable around 9-9-9-27 with 16GB, but I am pretty much an amateur when it comes to overclocking every last timing out of memory. For what its worth, they run very cool and are cheap.... no over the top heatspreaders that might block components

There is another possibility. K10Stat can raise voltage to. Just set 1.55 for 1.95 volts.

Anyone in here using a Asus f1a75-i deluxe itx board? I have a 3870k at 3.3 and gpu at 800mhz but cannot get my memory to even run at stock. Its corsair xms3 1600 rated at 7-7-7-20 2t 1.65volt. It crashes/bsod anything over 1333 even with 1.4volts to nb and running timings of 9-9-9-34. I think it is setting my secondary timings to tight but I don't know what to set them as. I know its not my ram as it ran at 1866 8-8-8-24 on last Intel board no probs. Tried a different stick of gskill 2133 and this also bsod anything higher than 1333. I am running the newest bios 602. Any ideas greatly appreciated!

Sorry hadn't checked this out in a few days. I just used easytune like you said, I haven't volt modded the board yet. Though I probably will when the contest is over. I am not sure if NB is the problem when you start maxing out. I have been pretty steadily been running it @ the max or even backed off a little and it hasnt kept me from pushing the chip further to much. My biggest enemy has been my subpar pot, and easytune. You can fairly easily raise the voltage past 2v on the vcore. 2.384v vcore is the highest i have gotten but it seems to either droop down, or not be registered as higher, My guess is its drooping .

Where is all the Llano action in here?

How does the internal GPUs overclock?
