Hi all, I'm new to the boards, actually joined to post this, though have been following the thread under 'guest' status. I'm reasonably computer savvy, built my first one ~14 years ago, but have been out of the loop for a while. About 6 weeks ago I decided to build an itx rig capable of htpc and gaming duty on a 52" flat screen.
Silverstone SG05 450w case (psu exhausting from case)
Samsung 2x4gb green/LV ram
Samsung 830 256GB SSD
Thermalright AXP-140 cooler with 120x15mm Gelid silent slim in pull with Delta PWM 70x15mm in push (stuck it between the heatpipes).
Stock intake fan replaced with a 120x25mm Cougar PWM fan
I added an HD 7870 at the end of last week. The install went fine of both card and drivers.
I set the machine up initially running off the HD4000 graphics, the Asrock had the 1.10 bios so I update to the current one available (1.70 at the time). I was running the cpu and ram at stock configuration. I noted my vcore was sitting in the .9s
, but didn't pay much attention beyond that so don't recall what it was specifically, other than in the .9s.
I did run IBT some to see how my cooling setup was performing in this perforated shoebox, and was seeing low-mid 60s on 100% load at the xtreme setting.
Now for my question, and please stifle any laughter......
Last Friday, after booting, I noticed windows was prompting me for a driver for an unknown device. I had made no changes to the hardware so went and looked up the ID, then googled it. It turns out it was for the Intel Smart Connect feature. This was odd, as I had disabled this in the uefi. I rebooted and entered the uefi and saw that Smart Connect was now set to 'enabled'. My usb mouse was also behaving very irratically within the uefi, which had never been an issue before. I had just read on here about issues with the 1.70 bios so I went to the asrock site intending to download the 1.60 for a downgrade. but noted the presence of a new 1.80 bios (and the aforementioned absence of 1.70). So I downloaded and flashed it and made all the necessary changes from defaults.
Everything has been fine since, but now my vcore idles at 1.032
. I know of no other changes made to the system besides the addition of the HD 7870, and can't think of anything that would alter vcore. I can't say that I noted the vcore after adding the HD 7870 and before updating to the 1.80 bios as they were within 24hrs of eachother, but am not sure how the addition of something in the pci-e slot would effect vcore. Temp yes, since it's blocking one side of the case, but the cpu still idles at about the same temp as before, and load was not affected much in IBT.So my question
, (yes, I googled it with no real results) Is it possible for the vcore to increase due to a bios change/update? If so, is this amount of change of any consequence? Or is there another reason I've completly overlooked as a noob?
I still have the 1.70 bios, and can try the 1.60 (but since I never ran it, it wouldn't really be a good test). I'm leary of downgrading to the 1.70 since it may have been giving me trouble, and doubt it's worth it over the curiousity of a change in vcore....although my curiousity is the reason for the post...
I do plan to overclock using offset mode to whatever this shoebox and cooling can handle (I know temps will be the problem and have my fingers crossed that it's not an abysmal failure).
I also noted my ram was defaulting to 1.585v (rated for 1.35/1.5). Yesterday I bumped it from stock of 1600 11-11-11-28 1T to 1866 9-9-9-24 1T at 1.45v and it seemed stable so far in HCI memtest. I have no plans to go higher as I already understand I'd be seeing minimal real world gains.
I'm sorry for the lengthy post, but wanted to provide as much info as possible.
Thanks in advance.
