AM1 5370 OC'D

[Davedree]

Hello I have been using a 5150 since Christmas and have been holding out for the 5370 since Jan. With the 5150 it runs at 1.6ghz and I was able to overclock it to a stable 2.05ghz, and for fun 2.3ghz.
With a x16 multi the 5150 is great value for clocking upto and beyond the stock 5350. However I wanted to see if I could hit 3ghz for some fun and the 5370 helped me achieve this with a 22x multi.

Here is the scaling of the 5370 from stock to 3ghz.





Power consumption at stock is 15w idle and 25-30w load.
At 3ghz the consumption is 35w idle and 70-75w load.

I use the am1 system as a htpc an so the stock cooler was used to it's limit at 2.8ghz at 1.450v temps were 55-58c on cinebench, temps are lower in normal usage but the little cooler wouldn't be ideal.

It was the last 200mhz that were hard work until I slapped a titan fenrir on it to keep temps below 50c. I just wanted to see if 3ghz was possible.

Any point in overclocking these apart from the fun?

I did it for fun and also to compare clock scaling and power consumption. I'd say if you have a 5150 then clocking to 2.05-2.10ghz with the memory oc'd is definetely recommended you can feel the difference over the 1.6ghz
The difference with the 5370 from 2.2 to 3ghz i 'd say is not worth it but 2.5-2.6ghz can easily be achieved with modest voltage and lowish temps.
I'd like to do some gpu scaling with a r7 360 or 750ti as i'd like to see if the overclock would help to feed the gpu next.

What board do you have? Did you have to make any compromises like setting sata to ide mode?

I've just bought a 5350 and mitx asus board from the mm. Looking forward to some fun clocking it.

Nice board same as mine
You are correct you set sata to ide instead of ahci and in doing so your usb3 ports will turn into usb2.0. You can get by with any ram as you have 4 memory mulitpliers but as you raise the ht ref over 137 you might start to lose igp stability. Make sure the power settings in windows are set right in balanced or you might not idle or see full performance.
Other than the power consumption can be excessive when over 2.5ghz make sure to have fun.

I also Have the Asrock because of the 4 sata and usb 3.0 connector and power brick connector but also i have the asus that allows overclocking but then no usb 3.0 and only 2 sata so its win and loose.
Not sure if to upgrade my 5350 to the 5370 it only provides the extra 200mhz clock speed.

I wouldn't spend money on a 5370 as your 5350 is more than capable. I like that asrock board with the onboard powersupply it's clever engineering.
They should have stuck a 25x multi on the 5370 really, it's so easy to achieve that.

Brill, thanks for the info. I'll have a go when I get it and update here with the results.

Go for it, look forward to it

Well done that's a fine result from the 5350.
What was the package temps getting to towards the end there?
These chips seem to hit a brick wall at 2.75-2.8ghz and seem to need big voltage to get past it. Did you lower the cpu multi to get your memory speed up?

 

[Davedree]

bear with me i am currently testing clockspeeds and using an R7 360 1200 1625 with a good mix of games

Here's the scaling of the 5370 in valley.

5370 1.6ghz 1600 9-9-9-24 1t



5370 2.2ghz 1600 9-9-9-24 1t




5370 2.8ghz 1666 9-9-9-24 1t

Cool! What overclock settings did you use to achieve the 2.8 and on which board?

I'm using the Asus Am1IA itx. I have a question about your board now you have overclock settings in the bios, do you have the ability to apply offset voltage to the cpu and when overclocking are you able to idle at reduced clocks and voltage?

This 5370 will easily run 2.8ghz, but it requires crazy voltage to get to 3ghz using 136 x 22 but at the moment my 2133 memory and cpu cooler are on my 2600k setup. So I've dialled the 5370 back to 2.8ghz and using 1600 memory oc'd to 1706.

2.8ghz setup consists of
Ahci off-
Ht Ref = 128
Cpu voltage offset + 0.2500
All power savings on.

If you are wondering if you are hitting the pci limit then one way to find out is to reduce your memory strap and your cpu multi and just keep incrementing the ht ref til either system doesn't boot, or drives seem flakey.
Also to note the nb frequency will increase with the ht ref too.
A good place to be is 2.5-2.6ghz.

Ok thanks for confirming, it seems there's a compromise in every board, I like your board for the onboard dc power, usb3 header and 4 satas. But I like my board for it's overclocking but it doesn't have a usb3 header.

By Ht Ref I mean Bclck, as you know default is 100.

The memory speed is calculated by multipliers of 4, 5.33, 6.66 or 8. In the bios memory frequency option you would see 800 / 1066/ 1333/1600.

So for example your cpu multi is 21 x 114mhz = 2394mhz.
Your ram speed with the 1600 option (x8 multi) is 114 x 8x2 = 1824mhz.
Your Nb speed will be 8 x 114= 912

So effectively as long as your memory timings are setup correctly you still have headroom to add more ht ref (=117 ). Even then you can just reduce the multi of the memory frequency down to the 6.66 strap and then work out how far your cpu/ht ref can be pushed without over stressing the memory.

2133 memory definitely helps though.

Yeah that is booger with the voltage limit.
Still if you've managed 2.5ghz then you certainly don't need a 5370.
